Are traits passed down through genetics? Yep. If you selectively breed the biggest angriest dogs together will you get more big, angry dogs? Yep. Behavioral traits have a low heritability but we are talking about thousands of generations bred specifically for killing and fighting. Of course on a small fucking time scale of a study there’s not going to be an obvious trend of traits passed from one generation to the next. That’s different than centuries of breeding. But please keep justifying your racist ass comparison to black people hexbear crackers you’re doing the lord’s work.
FUCKING THANK YOU
