In order for natural selection to operate on a trait, the trait must possess heritable variation and must confer an advantage in the competition for resources. If one of these requirements does not occur, then the trait does not experience natural selection.
Natural selection acts on the way organisms interact with one another and with their environment. The genes of organisms are not usually themselves involved in this intera â¦ ction: they direct it through intermediaries such as proteins. So natural selection must work through these intermediaries to affect genes.
