Allelic Frequencies of Four Phenotypic Traits of Tharu Tribes Along Nepal Border of Lakhimpur Kheri District of Uttar Pradesh, India

Abstract

The Tharu groups were randomly selected for four morphological and behavioural traits viz attached ear lobe, dimple in chin, widow’s peak, and tongue rolling to U-shape to obtain their allelic frequencies. The distribution of these four traits was shown in number as well as in percentage. The frequencies of dominant and recessive alleles of this group were also calculated. Their allelic frequencies have also been depicted because these characters are determined and inherited by single gene. The frequencies of recessive alleles were higher in all the phenotypes except ear lobe phenotype in which dominant allele (61.3%) is more prevalent than recessive allele (38.7%). Between males and females the allelic frequencies were higher in males than females except ear lobe frequency which was very close between male (38.1%) and female (39.9%). The present results have been compared with the previous data for the same traits reported from different districts of eastern Uttar Pradesh and other region of our country.
