I think that blaming one of your less desirable genetic traits on the parent that passed it down to you is pointless. Let’s use big ears as an example. If a guy has gigantic ears, he’ll most likely blame his big-eared father for passing down the gene. But everyone knows that you have no control over which genes you pass down and which ones you don’t. It’s not the father’s fault he has big ears. If anything, the dude should blame his mother for marrying the big-eared freak.
