Haplogroup K2b1 or K-P405 (sometimes known as Haplogroup S-P405), is a human Y-DNA haplogroup, defined by SNPs CTS5650, F3744 and P405.
Contents
K-P405 is found primarily in Melanesia (especially in Papua New Guinea), Micronesia and Maritime Southeast Asia.
Phylogeny
K2b1a has four primary subclades:
Distribution
The basal haplogroup K2b1a* (K-P405*) and the rest of K2b1axS are relatively rare. However, K2b1a* is found at significant levels among various Micronesian populations: 5.6%. It is also found among males on the Indonesian island of Sumba at a rate of 0.2%.
One study has reported finding S-M230 in: 52% (16/31) of a sample from the Papua New Guinea (PNG) Highlands; 21% (7/34) of a sample from the Moluccas (Maluku); 16% (5/31) of a sample from the Papua New Guinea coast; 12.5% (2/16) of a sample of Tolai from New Britain; 10% (3/31) of a sample from Nusa Tenggara, and; 2% (2/89) of a sample from the West New Guinea lowlands/coast. One subclade, Haplogroup S1d (S-M226.1) has been found at low frequencies in the Admiralty Islands and along the coast of mainland PNG.
