Effectiveness of microsatellite and single nucleotide polymorphism markers for parentage analysis in European domestic pigs.

Abstract

Parentage analysis and individual identification are recent, promising methods that have been applied to evolutionary and ecological studies, as well as conservation management. Parental exclusion relying on polymorphic microsatellites has been used worldwide in parentage determination, while the low mutation rate and genotyping error rate of single nucleotide polymorphisms (SNPs) make them another important marker for pedigree tracing. Here, we compared the effectiveness of microsatellites and SNP markers in European pigs. We also measured and presented the minimum and optimal criteria for SNP markers to be used in paternity and identity analysis. Our findings may contribute to the development of techniques for future molecular evolution and conservation studies, as well as breeding programs.
