Hi all,

I'll keep this post brief and straight to the point. I now have enough models/information I want to put into one place so its easier to find in future. Some of you may have ventured into or seen my SSA and Ashkenazi thread (https://anthrogenica.com/showthread.php?20374-Ashkenazi-and-Sub-Saharan-ancestry-tracing-using-segment-matches-and-G25-modelling) over in the Jewish section. That was in relation to my maternal grandfather. I recently received G25 coordinates for my father and noticed he was picking up smalls amounts of SSA (he's 50/50 Croatian and English). In brief discussions with Davidski and David Reich (as he was a co-author for the paper, The History of African Gene Flow into Southern Europeans, Levantines, and Jews, I thought his input would be valuable as well), we concluded my father likely has a small amount of SSA. With some feedback on modelling and guidance from our friend Angoliga, if he does have minor SSA, it is likely West African.

After modelling my father, I revisited myself and noticed I also pick up West African populations (smaller amounts). Here are some models, starting with OptimaFit's for my father (I include Sicilian because he seems to fit well with it, and it helps to decrease the SSA):

OptimaFit - Unscaled with penalty with Mandenka in the model

Sicilian West5.6
Mende Sierra Leone1.8

Optimafit - Unscaled with penalty without Mandenka in the model

Sample:Balkan Kiwi ► Balkan KiwiFather
Fit:0.9335

I'm not sure why including or removing Mandenka from the model changes which West African sample is selected. Someone here may be able to comment on this.
