... in the model is extreme endogamy for 50 full generations without any external DNA being added to the pot. We all know what happens in endogamy. Segments passed down multiple ways on multiple lines. This could very well be the reason for the expanded G values in their simulation. No external DNA added for 50 generations. If their ...
