Table 5 has admixture estimates of NE and SE Asians in Korean
populations; notice the gender asymmetry, with males of more
southern origin than females. Table S3 (Excel) has Y-chromosome
haplogroup frequencies. From the paper: What could be the origin
of the male-biased southern contribution to Korean gene pool
illustrated, for example, by haplogroups O-M122 (42.2%) and
O-SRY465 (20.1%) . Recent molecular genetic analyses and the
geographical distribution of haplogroup O-M122 lineages, found
widely throughout East Asia at high frequencies (especially in
southern populations and China), have suggested a link between
these Y-chromosome expansions and the spread of rice agriculture
in East Asia –. In general, Y-chromosomes might be spread via a
process of demic diffusion during the early agricultural
expansion period , . If this interpretation were substantiated,
the spatial pattern of Y-haplogroup O would imply a genetic
contribution to Korea through the spread of male-mediated
agriculture. PLoS ONE 10.1371/jou
