The TriversWillard hypothesis states that these organisms with this trait are favored if environmental conditions are good.
The TriversWillard hypothesis states that these organisms with this trait are favored if environmental conditions are good. According to Bateman's principle, organisms with this trait generally have greater variance in reproductive success. In haplodiploid systems, these organisms are the haploid ones. Among turtles, the number of organisms with this trait drops off as temperature increases. Birds with it are homozygous (*) ZZ. RA Fisher proposed that organisms with this trait will undergo runaway selection for other exaggerated useless traits. Some wrasses and parrotfish spontaneously acquire this trait during sequential hermaphroditism, and a scarcity of it may lead to parthenogenesis. For 10 points, name these organisms which, in humans, have a Y chromosome.
