Analysis Of Kinship Research Articles

Representation and Analysis of Kinship, Based on the Naming Pattern

In this study, we develop a graph-theoretic network model for genealogical data. It is based on the naming system used by the Galo tribe in the Indian state of Arunachal Pradesh. P-graphs are used to visually represent the genealogy. According to the analysis of the network on social network metrics, the genealogical network is a sparsely connected, scale-free network with an average path length of 11.615 and a graph density of 0.002. Only a small portion of its nodes have high centrality values. The network has three communities, twenty authority nodes, two hub nodes, and observed no relinking marriages.

METHODS OF KINSHIP ANALYSIS IN FOSSIL POPULATIONS

Introduction. Identifying kinship relationships from skeletal remains is among the various objectives of bioarchaeological studies. This article focuses on reviewing the methods used to analyze biological kinship in human fossil populations through non-metric traits. Methods. Since direct molecular-genetic analysis of kinship is often highly challenging due to the poor preservation of ancient DNA, special attention in such studies is given to nonmetric phenotypic traits. Results. Research with osteological samples that have been documented provides compelling evidence that the level of morphological similarity between individuals is directly related to their degree of biological kinship. In cases where the pedigrees of osteological materials are fully or partially known, phenotypic data can be effectively used in lieu of genetic information. Discussion. The methodology developed for kinship analysis depends on the internal spatial structure of the cemetery being studied. When analyzing small burial sites, the aim is to determine if the people buried there are close relatives. Various methods are used in these analyses, including different techniques for determining the likelihood of kinship, cluster analysis, and correlation coefficients. Identifying kinship is most promising in burial sites where archaeological or historical indicators of biological relationships are present. Kinship analysis in spatially structured cemeteries is aimed at identifying families or social groups. The analysis of uniformly distributed cemeteries focuses on identifying closely related individuals in large burials without clearly defined subgroups. This involves spatial correlation analysis, which tests for significant correlation between the matrix of spatial distances and the matrix of phenotypic distances; various counting methods to test for non-random clustering of traits; the nearest neighbor method; and a non-spatial block search procedure that simultaneously identifies presumed relatives and the traits that indicate the degree of their kinship. Conclusion. Many problems in establishing kinship can be overcome with the availability of skeletal material accompanied by verified genealogical data. Unfortunately, skeletal remains with preserved documentation are quite rare, limiting the opportunities to study the inheritance of non-metric traits and the morphological similarity of biologically related individuals.

Effect of uniparental disomy in parentage testing

Uniparental disomy (UPD) is a rare type of chromosomal aberration that may hinder the analysis of kinship during forensic identification. Here, we investigated these genetic findings to avoid false exclusions during parentage testing. Thirty-nine fluorescently labeled, autosomal short tandem repeats (STR) were amplified in three cases, to detect parent–child relationships. Twenty-three fluorescently labeled Y-chromosome STRs were also employed. These were subjected to capillary electrophoresis. The parentage index was calculated by the bipartite or tripartite model. Single nucleotide polymorphism (SNP) microarrays were performed to further investigate the genetic mechanisms. The conclusions supported the biological mother–child relationship in three cases. However, in all cases, the alleged father and child had three autosomal STR markers, constrained to a single chromosome, which did not conform to Mendelian inheritance rules. The genotyping of 23 Y-chromosome STRs did not reveal any violations of Mendelian law. The combination of STR profiling and SNP microarrays suggested that two children had maternal UPD of chromosome 7, whilst one had UPD of chromosome 2. After excluding the three incompatible loci, the conclusions supported the biological father-child relationship in all cases. The same results were obtained when parentage testing of trios was used. Uniparental disomy may complicate the judgment of kinship in parentage testing. The possibility of UPD should be considered when incompatible STR loci are found on the same chromosome. Genetic evidence obtained through additional molecular techniques can provide better interpretation of kinship in the presence of UPD and avoid false exclusions of biological relationships.

Evaluation of microhaplotype panels for complex kinship analysis using massively parallel sequencing

In recent years, microhaplotypes (MHs) have become a research hotspot within the field of forensic genetics. Traditional MHs contain only SNPs that are closely linked within short fragments. Herein, we broaden the concept of general MHs to include short InDels. Complex kinship identification plays an important role in disaster victim identification and criminal investigations. For distant relatives (e.g., 3rd-degree), many genetic markers are required to enhance power of kinship testing. We performed genome-wide screening for new MH markers composed of two or more variants (InDel or SNP) within 220 bp based on the Chinese Southern Han from the 1000 Genomes Project. An NGS-based 67plex MH panel (Panel B) was successfully developed, and 124 unrelated individual samples were sequenced to obtain population genetic data, including alleles and allele frequencies. Of the 67 genetic markers, 65 MHs were, as far as we know, newly discovered, and 32 MHs had effective number of allele (Ae) values greater than 5.0. The average Ae and heterozygosity of the panel were 5.34 and 0.7352, respectively. Next, 53 MHs from a previous study were collected as Panel A (average Ae of 7.43), and Panel C with 87 MHs (average Ae of 7.02) was formed by combining Panels A and B. We investigated the utility of these three panels in kinship analysis (parent-child, full siblings, 2nd-degree, 3rd-degree, 4th-degree, and 5th-degree relatives), with Panel C exhibiting better performance than the two other panels. Panel C was able to separate parent-child, full-sibling, and 2nd-degree relative duos from unrelated controls in real pedigree data, with a small false testing level (FTL) of 0.11% in simulated 2nd-degree duos. For more distant relationships, the FTL was much higher: 8.99% for 3rd-degree, 35.46% for 4th-degree, and 61.55% for 5th-degree. When a carefully chosen extra relative was known, this may enhance the testing power for distant kinship analysis. Two twins from the Q family (2–5 and 2–7) and W family (3–18 and 3–19) shared the same genotypes in all tested MHs, which led to the incorrect conclusion that an uncle-nephew duo was classified as a parent-child duo. In addition, Panel C showed great capacity for excluding close relatives (2nd-degree and 3rd-degree relatives) during paternity tests. Among 18,246 real and 10,000 simulated unrelated pairs, none were misinterpreted as a relative within 2nd-degree at a log10(LR) cutoff of 4. The panels presented herein could provide supplementary power for the analysis of complex kinship.

Kinship, Genealogy, Objectivity, and Ethnocentrism

This describes the factual and epistemological mistakes leading to the collapse of anthropological interest in the scientific analysis of kinship and social organization in the 1980s, their persistence to the present, and the alternative that avoids them. The basic argument is that while kinship was and is a challenging topic, the reason for the collapse of kinship studies in response to David Schneider's criticism in 1987 had did not reflect those inherent problems.  They reflected self-contradictions and counter-factual assumptions in the conceptions of science, meaning, and objectivity in the approaches that were taken to it, both by those Schneider criticised and by Schneider himself.The paper details the steps by which those errors accumuluted in this particular line of argument.  It does so in part by contrasting this line with my own approach that avoided them, and that Schneider knew about but evidently did not understand.

Complex kinship analysis with a combination of STRs, SNPs, and indels

Complex kinship analysis has been widely applied in disaster victim identification and criminal investigations. A larger number of genetic markers is required to improve the discrimination power of the system in complex kinship analysis compared to that in paternity testing, as distant relatives share fewer genetic segments. Genetic markers, including short tandem repeats (STRs), single-nucleotide polymorphisms (SNPs), and insertions-deletions (indels), play complementary roles in kinship analysis. Few studies have systematically analyzed the system discrimination power of a new combination of different types of genetic markers before using these markers in practice. Here, we tested the ability of a set of 56 STRs available in commercial panels on complex kinship analysis. We next introduced a combination marker set of STRs, indels, and SNPs and evaluated the system discrimination power of 72 indels + 52 SNPs to improve the weight of 56 STRs. Statistical analysis of complex kinship within third-degree kinship testing was performed to compare 56 STRs or 72 indels + 52 SNPs alone. True samples were assessed, including 99 full siblings, 112 uncle/aunt-nephew/niece, 43 grandfather/grandmother-grandson/granddaughter, 63 first cousins, and 5931 unrelated pairs. Simulation was also performed using 10,000 pairs of relatives and 10,000 unrelated individuals. The effectiveness of the three marker sets in kinship testing was ranked as follows: 56 STRs + 72 indels + 52 SNPs > 56 STRs > 72 indels + 52 SNPs. All three marker sets were powerful in first-degree kinship testing; 56 STRs and 56 STRs + 72 indels + 52 SNPs could distinguish most second-degree relatives from unrelated pairs. However, only a portion of third-degree relatives was correctly determined from unrelated individuals using 56 STRs + 72 indels + 52 SNPs. In relationship testing, 56 STRs and 56 STRs + 72 indels + 52 SNPs were powerful enough to distinguish first-degree relatives from second-degree or third-degree relatives. Our results provide a strategy and guidance applicable in forensic practice for complex kinship analysis by combining STRs, SNPs, and indels.

Jenis dan Kekerabatan Kupu-Kupu (Lepidoptera) di Taman Hutan Raya Sulawesi Tengah

Species and cladystic of butterflies is closely related to the preservation and utilization of biological resources in Indonesia. This study aims to determine species and cladystic of butterflies (Lepidoptera) in Grand Forest Park Central Sulawesi. Sampling of butterflies using a sweeping net with a purposive sampling method at three different watershed (DAS) locations, namely Vatutela, Kawatuna, and Poboya. Butterfly samples obtained at the research location were then identified at the Biology Laboratory, Faculty of Teacher Training and Education, Tadulako University. The results showed that there were 97 species from 5 butterfly families, namely Papilionidae (14 species), Pieridae (16 species), Nymphalidae (46 species), Lycanidae (15 species), and Hesperiidae (6 species). The research sample used for the analysis of kinship is 23 species from five butterfly families that dominate the research location. The observed characters included 32 characters. Analysis of kinship was calculated using the Sorensen similarity index, then processed using the Multivariate Statistical Package (MVSP) software. The closest kinship relationship is between the species Appias ithome and A. zarinda which is supported by a similarity index above 0.90 and the farthest relationship occurs between the species Bibasis sp. with other species from the Hesperiidae family which were supported by a similarity index below 0.7.

Statistical analysis in support of maintaining a healthy traditional Siamese cat population

BackgroundFor many years, breeders of companion animals have applied inbreeding or line breeding to transfer desirable genetic traits from parents to their offspring. Simultaneously, this resulted in a considerable spread of hereditary diseases and phenomena associated with inbreeding depression.ResultsOur cluster analysis of kinship and inbreeding coefficients suggests that the Thai or traditional Siamese cat could be considered as a subpopulation of the Siamese cat, which shares common ancestors, although they are considered as separate breeds. In addition, model-based cluster analysis could detect regional differences between Thai subpopulations. We show that by applying optimal contribution selection and simultaneously limiting the contributions by other breeds, the genetic diversity within subpopulations can be improved.ConclusionIn principle, the European mainland Thai cat population can achieve a genetic diversity of about 26 founder genome equivalents, a value that could potentially sustain a genetically diverse population. However, reaching such a target will be difficult in the absence of a supervised breeding program. Suboptimal solutions can be obtained by minimisation of kinships within regional subpopulations. Exchanging animals between different regions on a small scale might be already quite useful to reduce the kinship, by achieving a potential diversity of 23 founder genome equivalents. However, contributions by other breeds should be minimised to preserve the original Siamese gene pool.

Survey on the Analysis and Modeling of Visual Kinship: A Decade in the Making.

Kinship recognition is a challenging problem with many practical applications. With much progress and milestones having been reached after ten years, we are now able to survey the research and create new milestones. We review the public resources and data challenges that enabled and inspired many to hone-in on the views of automatic kinship recognition in the visual domain. The different tasks are described in technical terms and syntax consistent across the problem domain and the practical value of each discussed and measured. State-of-the-art methods for visual kinship recognition problems, whether to discriminate between or generate from, are examined. As part of such, we review systems proposed as part of a recent data challenge held in conjunction with the 2020 IEEE Conference on Automatic Face and Gesture Recognition. We establish a stronghold for the state of progress for the different problems in a consistent manner. This survey will serve as the central resource for the work of the next decade to build upon. For the tenth anniversary, the demo code is provided for the various kin-based tasks. Detecting relatives with visual recognition and classifying the relationship is an area with high potential for impact in research and practice.

Морфо-физиологические особенности дикорастущих образцов тимофеевки луговой (Phleum pratense L.)

The research was carried out in the field at the Central experimental base of the Federal Williams Re¬search Center. The object of research was 12 samples of wild-growing meadow timothy grass. Samples were sown according to the scheme of a standard collection nursery. All studies and observations were carried out on the herbage of the 2nd and 3rd year of life. Statistical processing of results of researches of meadow timothy indicates a low level of variation in the main morphological and physiological characte¬ristics. Only by the number of vegetative shoots have the coefficient of variation reach 35.8%. Samples 416 and 419 were distinguished by precocity, samples 406 and 419 by the height of plants during flower¬ing, sample 412 by the number of generative shoots, and sample 412 by the yield of air-dry mass. Sam¬ples 409 and 414 were distinguished by the length of the sultan, and the weight of seeds — 414 and 415. Nine reliable correlations were found at the significance level 05 and 01. However, all of them are related to the yield of the number of generative and vegetative shoots. Using the binomial equation, the experi¬mentally obtained variability of dry mass yield from the number of generative and vegetative shoots by 93.1% is described. The optimal productivity of meadow timothy grass stand for generative shoots in the area of 550–600 shoots, and vegetative ones — in the area of 320–350 shoots per square meter. Analysis of remoteness and kinship between samples showed the presence of 2 clusters (genetically different quality groups), which can be used for combinational ability selection and fixing of selection-valuable features and properties.

IDENTIFIKASI MORFOLOGI DAN KEKERABATAN SALAK DI JAWA TIMUR

Salak has the scientific name Salacca zalacca including a low-growing family of palms. This seasonal fruit plant is a type of horticulture that has the potentioal to become an axport commodity in Indonesia. In East Java, especially in Lumajang, Madura and Kediri are areas that produce salak commodities. Morphological identification aims to obtain basic traits so that the appearance or phenotype of each accession can be distinguished quickly and easily, by estimating how much genetic diversity it has. This study aims to determine the morphological characters and to determine the salak kinship of Lumajang, Kediri and Madura. The result of phylogeny analysis of the Salacca zalacca kinship in East Java show that the results of the kinship analysis of the salak in the Lumajang, Kediri and Madura areas formed 2 large groups or cluster. So it can be concluded that the Salacca zalacca originating from the Lumajang, Kediri and Madura areas still come from the same ancestor. This can be seen from the value of kinship distance, the morphological identificaion equation. In addition, environmental factors can also affect the morphology of plants. Sunlight intensity, N and P nutrients can also affect the difference in leaf color

Migration and the invisible economies of care: Production, social reproduction and seasonal migrant labour in India

This paper focuses on the processes of migrant labour exploitation which are crucial for capitalist growth and the inequalities they generate. Ethnographic research conducted in different sites across India shows how patterns of seasonal labour migration are driven by class relations marked by hierarchies of identity (caste and tribe) and the spatial geopolitics of internal colonialism (region) – differences that are mobilised for accumulation. Labour migration scholarship has mainly explored sites of production. We extend recent social reproduction theory (SRT) and an older literature on labour migration and reproduction to argue that the intimate relationship between production and social reproduction is crucial to the exploitation of migrant labour and that this means we have to place centre‐stage the analysis of invisible economies of care which take place across spatiotemporally divided households, both in the place of migration and in the home regions of migrants. Furthermore, we develop recent work on SRT and migration to argue that an analysis of kinship (gender over generations, not just gender) is crucial to these invisible economies of care. This analysis is important in showing the machinations of capitalist growth and for political alternatives.

RETHINKING NAVAJO SOCIAL THEORY

Author(s): Shapiro, Warren | Abstract: Hal Scheffler, in arguing that native concepts about procreation provide the basis for kin reckoning universally, presented considerable evidence for his argument, in addition to the extension rules for which he is best known, This essay applies this evidence to the Navajo materials and shows that a Schefflerian analysis is correct. By contrast, the analysis of Nava-jo kinship by Gary Witherspoon, indebted to David Schneider’s ideas, is shown to be wide of the mark. Scheffler also argued, in much the same logical vein, that gender classification around the world is bipartite, that claims of a “third sex” are without merit. The argument is applied to “third sex” claims by Wesley Thomas, which claims are shown to be baseless.

Modeling and synthesis of kinship patterns of facial expressions

Analysis of kinship from facial images or videos is an important problem. Prior machine learning and computer vision studies approach kinship analysis as a verification or recognition task. In this paper, for the first time in the literature, we propose a kinship synthesis framework, which generates smile and disgust videos of (probable) children from the expression videos (smile and disgust) of parents. While the appearance of a child's expression is learned using a convolutional encoder–decoder network, another neural network models the dynamics of the corresponding expression. The expression video of the estimated child is synthesized by the combined use of appearance and dynamics models. In order to validate our results, we perform kinship verification experiments using videos of real parents and estimated children generated by our framework. The results show that generated videos of children achieve higher correct verification rates than those of real children. Our results also indicate that the use of generated videos together with the real ones in the training of kinship verification models, increases the accuracy, suggesting that such videos can be used as a synthetic dataset. Furthermore, we evaluate the expression similarity between input and output frames, and show that the proposed method can fairly retain the expression of input faces while transforming the facial identity.

Transverse basilar cleft: Two more probable familial cases in an archaeological context

AbstractTransverse basilar cleft (TBC) is a very rare congenital anomaly representing a coronal fissure completely or partially intersecting the basioccipital at the level of the pharyngeal tubercle. It is usually asymptomatic but can sometimes be part of a syndrome. Population frequencies of this anomaly are no more than 1%, with few exceptions. Two skulls with TBC were found in the Ayrydash 1 cemetery of Altai Mountains nomads, Russia, attributed to the Hunno‐Sarmatian period (2nd c. BC–5th c. AD). In this paper, we test the possibility of a familial relationship between the individuals who shared by this condition, using the Alt and Vach method for nonspatial analysis of skeletal kinship based on cranial and dental nonmetric traits. Results of the study show that the frequency of TBC is significantly higher in the Ayrydash 1 sample than in the rest of the skeletal population from the Hunno‐Sarmatian period (p < 0.05). This suggests that the individuals affected by TBC were most likely genetic relatives. The observed clustering of TBC and some other rare anomalies within local groups of Altai Mountains nomads appears to be due to parental consanguinity in their community.

COMPARATIVE ANALYSIS RESULT OF LOCAL PADDY KINSHIP BASED ON QUANTITATIVE AND QUALITATIVE CHARACTERS

Morpho-agronomic characters consist of two types of qualitative and quantitative characters. Qualitative characters were discontinuous and score data form, while the quantitative are continuous and measurable. Kinship analysis is important for breeders to know the genetic distance between genotypes. Allegedly there are differences in the genetic kinship analysis between based on data from qualitative to quantitative character. The aim of this study was to compare the results of the analysis of kinship based on quantitative and qualitative data on phenotypic characterization of local rice. A total of 43 local rice from West Java was used on phenotypic characterization activities. The research was done at Sukamandi experiment station of ICRR (Indonesian Rice Research Institute) on 2014. Qualitative characters were observed as many as 24 characters, and quantitative as many as 23 characters. Analysis of data was by using Minitab version 14. The results indicate that kinship analysis results using data from qualitative, quantitative or a combination of both was not significantly different at the component level analysis of the number of clusters and similarity but there were real differences in the level of genetic distance. Dendogram based on qualitative characters was different than based on quantitative character. Analysis of kinship between genotype recommended using a data combination of qualitative and quantitative character that the genetic distance between genotype information more accurately
