摘要
The highly structured distribution of Y-chromosome haplogroups suggests that current patterns of variation may be informative of past 族群 processes. However, limited 系統發育 resolution, particularly of subclades within haplogroup K, has obscured the relationships of lineages that are common across Eurasia. Here we genotype 13 new highly informative single-nucleotide polymorphisms in a worldwide sample of 4413 males that carry the derived allele at M526, and reconstruct an NRY haplogroup tree with significantly higher resolution for the major clade within haplogroup K, K-M526. Although K-M526 was previously characterized by a single polytomy of eight major branches, the 系統發育 structure of haplogroup K-M526 is now resolved into four major subclades (K2a-d). The largest of these subclades, K2b, is
