Don't read things that don't exist. I never said that only males were conceived as a matter of fact I never mentioned the sex of the children. And you're right, if a baby girl has a dad with a large penis and somewhere down the line she has a son he could very well get his grandpa's big dick. And he could later have a son or daughter that can pass down that same trait and it can continue from generation to generation.
Simply put what I was saying is that if males with the biggest genitals are preferred for procreation it's obvious that that trait will likely be passed on to his offspring and he will have more offspring than the non preferred males. That is not a botched history lesson it's common sense LOL.
Also, as I said in my original post, in multicultural societies the differences in penis size of races is less significant than it was generations ago. But to gloss over the history of how this stereotype got started is foolish. I don't see you questioning any other part of my botched history lesson like how slaves were treated like cattle, how they were sold, how they were forced to have children and then had those children taken away and sold. Was any of that wrong?
