bugs have a fascinating version of "BP" and it is useful too.paulsamuel said:just a note, after all that, sexual selection is mostly females choosing males (in fact, I cannot think of any where the female is the object of selection), so switch the sexes and the gene to BP (you can guess what BP is).
i can't think of any off the top of my head but i'm sure they exist. i can say, with no proof at all- just guessing, that humans do. there are more females than males, so males would be the selecting sex. plus females of this species peacock themselves to attract mates. i'll consult the literature and get back to this.
