An analysis of 16 Ainu male individuals found that the majority (14/16) belong to Y-DNA Haplogroup D-M55, while a minority (2/16) belongs to Haplogroup C-M217. D-M55 is found throughout the Japanese archipelago, with very high frequencies among the Ainu of Hokkaido. C-M217 is found more commonly among populations from Northeast Asia and Central Asia. Another analysis found that one out of four Ainu men belonged to haplogroup C-M217, while the remaining three belonged to haplogroup D-M55.
