Özet

By its paternal transmission, Y-chromosomal haplotypes are sensitive markers of population history and male-mediated  introgression.  We  used  whole-genome  sequences  (WGSs)  of  386  domestic  goats  from  75 modern breeds and 7 wild goat species generated by the VarGoats goat genome project. Phylogenetic analyses indicated five domestic haplogroups Y1AA, Y1AB, Y1B, Y2A and Y2B. Haplogroup distributions for  180  domestic  breeds  indicate  ancient  paternal  population  bottlenecks  during  the  migration  into  northern Europe, southern Asia and Africa. Sharing of haplogroups reveals male-mediated introgressions: from  Asia  into  Madagascar  and,  more  recently,  into  the  South-African  Boer  goat;  then  from  this  breed  into other southeastern African goats; and from Europe into native Korean and Ugandan goats. This study illustrates the power of the Y-chromosomal variation for the reconstructing the history of domestic species with a wide geographic range.
