Paternal Lineage Analysis in Sahiwal, Cholistaniand Dajal Cattle Breeds of Pakistan through SRY gene

摘要

This was the first study conducted to determine the origin and genetic diversity of Pakistani cattle(Cholistani, Sahiwal and Dajal). We analyzed SRY gene sequences of 60 samples, together with the availablesequences in GenBank. The sequence of SRY gene is conserved in Pakistani cattle having no SNP.The neighbor joining tree showed that Pakistani cattle mostly originated from Bosindicus. To determine thepercentage of genetic divergence for SRY gene in bovine and out-group, the p-distance model was used in theanalysis. A very short genetic distance was found between our haplotypes (Sahiwal, Cholistani and Dajal) andBosindicus (0.01%), showing a very high genetic similarity.
