Latin American users PCA maps

[Kriptc06]

This thread is meant to show the diversity in Latin America with a PCA map.

Run your genome through Eurogenes K15 and use this tool:

If you are a tested latam or is related to it, please, post your Y and X axis and I will add you to the map.

Add me bro

Abscisse (x-axis): 530 pixel
Ordonnée (y-axis): 412 pixel

[Wrong]

Plotting map gets skewed due to Caucasian groups there being inbetween Amerindian/Asian and SSA.

Yoruba & Selkup mix plots near Saudi for example..

i think you are right, another map with the 3 in a triangle position would be better

[PunhetaDeBacalhau]

The distances between the components in that map are not based on FST distances and are therefore meaningless. Amerindian is at the same distance from Eastern Euro as Eastern Euro is from Baltic... It leads to wrong conclusions.

This pca map is not accurate for racially admixed people, works solely for non admixed people.

Which is right, ANE (close to "Eastern") is between WHG and Amerindian at world scale, Amerindians are between ANE and East Asians, that's what they get it's well known and easy to verify when placing ancient samples, it's maybe not the absolute best calc for ancient but the general idea is still right. The pca is based on Fst relationships of course.

Nevertheless, I shall proceed to add my compadres

FST distance between Amerindian and Eastern Euro: 0.128

FST distance between Baltic and Eastern Euro: 0.024

0.024/0.128 = 0.1875.

Eastern Euro should be a bit over 5 times closer to Baltic in comparison to Amerindian. In the PCA, they are at the same distance. How is this right exactly? Funnily enough, even the Siberian component is closer to Eastern Euro (0.1 distance) than Amerindian. Amerindians have been isolated for a long time, they've drifted into their own people genetically speaking.
