Reference I Admixture Analysis K=10-12

A week later, some more Admixture analysis of Reference I dataset.
As usual, the results are available in a spreadsheet, which is also listed on my sidebar.


Let's start with K=10.

C1	South Asian	C2	Kalash
C3	Southwest Asian	C4	Southeast Asian
C5	European	C6	Papuan
C7	Northeast Asian	C8	Siberian
C9	West African	C10	East African

The addition here is basically of the Siberian component which is highest among the Yakut.

Fst divergences between estimated populations for K=10:

	C1	C2	C3	C4	C5	C6	C7	C8	C9
C2	0.057
C3	0.064	0.073
C4	0.089	0.127	0.136
C5	0.063	0.061	0.038	0.131
C6	0.167	0.209	0.215	0.202	0.210
C7	0.080	0.120	0.129	0.032	0.123	0.190
C8	0.085	0.117	0.127	0.059	0.118	0.203	0.039
C9	0.152	0.174	0.161	0.201	0.171	0.266	0.195	0.199
C10	0.115	0.133	0.117	0.166	0.128	0.233	0.160	0.163	0.036

Now for K=11,

C1	South Asian	C2	Kalash
C3	Southwest Asian	C4	Southeast Asian
C5	European	C6	Papuan
C7	Siberian	C8	Northeast Asian
C9	East African Bantus	C10	West African
C11	East African

C8 at K=11 is now modal among the Han instead of the Japanese. This affected the Southeast Asian C4 component which is now more of a real Southeast Asian one.

The new ancestral component C9 is among the Bantus of eastern and southern Africa. It is highest among the Luhya and Bantus of Kenya.

Fst divergences between estimated populations for K=11:

	C1	C2	C3	C4	C5	C6	C7	C8	C9	C10
C2	0.055
C3	0.062	0.072
C4	0.081	0.120	0.128
C5	0.063	0.063	0.038	0.124
C6	0.169	0.211	0.215	0.195	0.213
C7	0.089	0.128	0.135	0.057	0.130	0.203
C8	0.083	0.122	0.131	0.031	0.127	0.194	0.039
C9	0.143	0.165	0.150	0.185	0.162	0.259	0.195	0.189
C10	0.152	0.174	0.160	0.194	0.172	0.268	0.203	0.198	0.014
C11	0.104	0.122	0.101	0.149	0.115	0.226	0.158	0.152	0.037	0.043

At K=12,

C1	South Asian	C2	Balochistan/Caucasus
C3	Kalash	C4	Southeast Asian
C5	Southwest Asian	C6	European
C7	Papuan	C8	Northeast Asian
C9	Siberian	C10	East African Bantus
C11	West African	C12	East African

The Kalash component has split, with an assist from Southwest Asian, into a pure Kalash component (C3) and a Balochistan/Caucasus (C2) which is highest in Southwestern Pakistan (Brahui, Makrani, Balochi) at 60-57% followed by Georgians, Lezgin, Adeygei, Azerbaijan Jews and Iranian Jews (56-50%).

The Southwest Asian component (C5) is now more of a Southwest Asian and North/Northwest African component. The West Asian element in it has been reduced.

The Northeast Asian component (C8) is now again centered on Japan. I have a solution for this movement which I'll apply in my next round of analysis.

Fst divergences between estimated populations for K=12:

	C1	C2	C3	C4	C5	C6	C7	C8	C9	C10	C11
C2	0.057

Higher K value admixture analysis will continue
