why is one of my sisters so ugly? I have three sisters, one is ugly asf, one is average, and the last one is beautiful she looks similar to me, Im a male and I know for a fact im handsome and cute. Im not saying I find my family attractive but I can see when someone is ugly or not. Both my parents I would say are average. Its just surprising to me I share DNA with such an ugly thing and average sister. You would think if one child is beautiful rest would be too. I hope my children wont be ugly(they shouldnt be due to my face but since I share similiar DNA to an ugly person maybe it could happen) I will make sure to get a good looking woman so the chances of it happening are low.
