I was just thinking, some animals can change gender if there`s no female around and still make children, does that mean that we humans or more exact, boys, creates life inside themselves? I mean, if you look at a spermie, they look kinda fully developed with personality and everything just having fun before they enter an egg to grow bigger from air and nutrients, so when the spermie later looks like it`s parents, they`re just trying to mimick the looks of them, so it`s not really genes that makes our looks but how we try to look alike?
