Y-chromosome genetic diversity of Bos indicus cattle in close proximity to the centre of domestication.

摘要: Y-chromosome genetic diversity in and around its domestication origin a better understanding of indicine-specific microsatellite alleles are imperative concerns but less -targeted. We analysed markers 301 bulls representing 19 native Indian cattle (Bos indicus) identified new haplotypes. Compared to other indicine studies, the high Y-haplotype found supports hypothesis greater variability across centre decreasing along migratory routes with increasing distance. Hence, considerable paternal appears have been lost transboundary commercial breeds. The Khillar Gir most diversified populations where first tends be well-differentiated traditional breed carrying strikingly distinct Y-lineages typical BM861-158 bp allele, characteristics taurine cattle, while retaining standard lineages for all markers. Geographical distribution an unreliable predictor parental variation, seemed closely related function/utility. comprehensive information will useful examine demographic expansion/spread Bos indicus from close proximity different countries worldwide such should preserved through effective management conservation programs.
