Where do you think a half Tikar (or Yoruba) half somali would plots in the PCA I posted? Because the Sanye (cushitic) above Kikuyus is already closer to Somalis than to unadmixed Niger-Congo by a margin. If they were a direct mix of these two populations, they would be 65%somali 35%West africanKikiyus are about 35 % Cushitic on average. But those Somali bantu samples look like they cluster near the lower end of the Kikiyu samples which is why they appear to be around 30 %.
