Haplogroup Y has been found with high frequency in many indigenous populations who live around the Sea of Okhotsk, including approximately 66% of Nivkhs, approximately 43% of Ulchs, approximately 40% of Nanais, approximately 21% of Negidals, and approximately 20% of Ainus. It is also fairly common among indigenous peoples of the Kamchatka Peninsula (Koryaks, Itelmens) and among certain Austronesian peoples (especially groups closely related to Native Taiwanese).
The distribution of haplogroup Y in populations of the Malay Archipelago contrasts starkly with the absence or extreme rarity of this clade in populations of continental Southeast Asia in a manner reminiscent of haplogroup E. However, the frequency of haplogroup Y fades more smoothly away from its maximum around the Sea of Okhotsk in Northeast Asia, being found in approximately 2% of Koreans and in South Siberian and Central Asian populations with an average frequency of 1%.
The Y2 subclade has been observed in 40% (176/440) of a large pool of samples from Nias people in western Indonesia, ranging from a low of 25% (3/12) among the Zalukhu subpopulation to a high of 52% (11/21) among the Ho subpopulation.
