Through several advanced calculations, they concluded that even a small relative amount of sexual antagonism will overwhelm any benefit harvested from sexually concordant selection. But our bones likely tell a very different story.
These factors can be in the form of promoter regionswhich can be either suppressed or activated by hormones. Sex-limited characteran observable feature appearing only in members of one sex of a given population of organisms, although organisms of both sexes may have the genetic constitution that determines the trait.
For example, while they allow for greater opportunities of sexual dimorphism so both sexes can reach much closer to their optimal phenotypes, they also incur fitness costs on sexually reproducing species.
