The dichotomy structure of Y chromosome Haplogroup N
Kang Hu et al.
Haplogroup N-M231 of human Y chromosome is a common clade from Eastern Asia to Northern Europe, being one of the most frequent haplogroups in Altaic and Uralic-speaking populations. Using newly discovered bi-allelic markers from high-throughput DNA sequencing, we largely improved the phylogeny of Haplogroup N, in which 16 subclades could be identified by 33 SNPs. More than 400 males belonging to Haplogroup N in 34 populations in China were successfully genotyped, and populations in Northern Asia and Eastern Europe were also compared together. We found that all the N samples were typed as inside either clade N1-F1206 (including former N1a-M128, N1b-P43 and N1c-M46 clades), most of which were found in Altaic, Uralic, Russian and Chinese-speaking populations, or N2-F2930, common in Tibeto-Burman and Chinese-speaking populations. Our detailed results suggest that Haplogroup N developed in the region of China since the final stage of late Paleolithic Era.

ReplyDeleteUnfortunately he does not precise what part of China North or South?
This is quite important for the question of R and Q.
"Unfortunately he does not precise what part of China North or South?"
ReplyDeleteThe distribution suggests a reasonably northern origin within China. Quote:
"all the N samples were typed as inside either clade N1-F1206 (including former N1a-M128, N1b-P43 and N1c-M46 clades), most of which were found in Altaic, Uralic, Russian and Chinese-speaking populations, or N2-F2930, common in Tibeto-Burman and Chinese-speaking populations".
All the N1-F1206 clades are 'northern' and the F2930 also tend to be northern in origin at least.
"This is quite important for the question of R and Q".
Not really. Q/R and N/O have recently been demonstrated as completely separate branches within K2. NO being classified as K2a, with K2b, K2c and K2d being primarily SE Asian, while QR is K2b2, with the K2b1 branch being primarily east of Wallace's Line. The region of NO's origin would therefore give not the slightest hint as to the region of QR's origin.
