Quizplus · Accepted Answer

Intrasexual selection is the type of natural selection that leads to competition between individuals of the same sex for the opportunity to mate with individuals of the opposite sex. In this case, male beetles with larger horns have a competitive advantage over other males, allowing them to win more fights and access more females for mating. This results in the selection of traits that enhance their ability to win these fights, such as larger horns, and is an example of intrasexual selection.
