Chinese Cattle Y-SNP Haplotypes and Paternal Origin
To determine the genetic diversity and paternal origin of Chinese cattle, 284 male samples from 16 Chinese native cattle breeds were analyzed using four previously defined Y-SNP markers that distinguish between taurine and indicine cattle.In Chinese bulls, the taurine Y2 haplogroup and indicine Y3 haplogroup were detected in 162 (57.0%) and 122 (43.0%) individuals, respectively,although these frequencies varied amongst the Chinese cattle breeds examined.Y2 dominates in northern China (98.2%), while Y3 dominates in southern China (83.5%).Central China is an admixture zone, although Y2 predominates overall (64.5%).The geographical distributions of the Y2 and Y3haplogroup frequencies reveal a pattern of male indicine introgression from south to north China, and male taurine introgression from north to south China.
