Ref3 + Harappa Maps

More maps from The Jatt Gene using the Reference 3 and Harappa participants K=11 admixture results.

C1 South Asian Isopleth

C2 Onge Isopleth

C1 South Asian Chloropleth at state/province level

C2 Onge Chloropleth

As usual, Simranjit has more maps on his blog.

Admixture Onge Component Map

Since the Onge component on my K=11 admixture run was very strongly correlated with Reich et al's Ancestral South Indian (r2Simranjit has been kind enough to let me share his map of the Onge component in South Asia.

He also has maps of the K=12 admixture run.

Harappa Maps

Simranjit has generated new isopleth maps from the latest K=12 admixture run.

C1 South Asian:

C2 Balochistan/Caucasus:

C5 Southwest Asian:

C6 European:

Simranjit's also creating isoclusters now which classify different points/regions into clusters based on the admixture results Simran is using from here. Here's an isocluster map with 15 clusters inferred from the K=12 admixture results of reference populations and Harappa participants.

You can see the dendrogram showing the distance between the clusters on his blog.

Harappa Maps

Here are a couple of more maps of the South Asian admixture component from Simranjit incorporating the latest Harappa results.

He's posted more maps at his blog.

Admixture K=17 maps: Mediterranean and Southwest Asian

From the Reference I K=17 Admixture results, Simranjit has created more isopleth maps.

Mediterranean component:

Southwest Asian component:

More Admixture Maps

Simranjit has sent more maps incorporating the latest admixture results.

C1 South Asian:

C2 Balochistan/Caucasus:

C6 European:

South Asian Map

Simranjit has another map:

I am working on improving the interpolation algorithm to take into account barriers such as oceans and even terrain features like mountain ranges. However, this process takes a long time.

Anyways in the meantime , this is one i think the participants would be interested in. It has several things in it, an isopleth layer for C1 - South Asian (12 gradations for more impact). It also have the other Components (C1, C2, C3, C4, C5, C6, C8) represented in the form of pie charts. Base map is a topographic one this time.

Harappa Participant Admixture Maps

Following maps of the reference populations, Simranjit has gone ahead and included the Harappa Project participants in these maps as well.

Here's what he said:

I'm now incorporating project participants into the maps. I had to drop admixed individuals, however, and I made some choices, dropped the Bihari Kayastha and the Tamil Nadu non-Brahmin for now, as they differ a fair bit. Take note that as we don't have reference sample for some countries so this sometimes can cause the interpolation to be off (e.g. lack of Central Asian republics other than Uzbekistan is skewing Central Asia to be more South Asian than it really is).

These maps are based on K=12 admixture run.

The gradation is from Dark green (low) to Dark red (high) for most of them.

Basically the percentages for each Component are divided into 32 equal intervals, to create the contour effect. Take note that it represents relative values not absolute.

C1 South Asian component:

C2 Balochistan/Caucasus component:

C6 European component:

Isopleths

Simranjit has done a great job of creating some maps showing the distribution of the various ancestral components at K=16. He has posted them on DNA Forums and sent them to me.

The gradation is from Dark green (low) to Dark red (high) for most of them.

Here is C1 South Asian:

C2 Balochistan/Caucasus:

C5 Southwest Asian:

C6 European:

C12 Siberian:

Great job, Simranjit!
