Origin and post-glacial dispersal of mitochondrial DNA haplogroups C and D in northern Asia.

More than a half of the northern Asian pool of human mitochondrial DNA (mtDNA) is fragmented into a number of subclades of haplogroups C and D, two of the most frequent haplogroups throughout northern, eastern, central Asia and America. While there has been considerable recent progress in studying m...
