Question

Starting with fundamental difference between the sexes, explain why males tend to be under stronger sexual selection than females.

Answer 1

Intrasexual competition between male and females choice of mating is common according to recent studies. Darwin suggested that when males and females have different habits and differs in traits other than primary sexual characters, these are because of natural selection. Females produce less and non motile gametes whereas males produce comparitvely more and motile. Males compete among themselves for accessing females whereas females tend to be choosy and tend to mate with only particular preferred males. Particularly in birds and mammals, males are often stronger than females. Males benefit from frequent mating. Several studies suggest that there is a connection between harmone levels and partner selection among humans. Females selects strong male with some traits like height, muscular body, facial shape etc for reproduction. Males look for traits in females like body shape, voice etc while selecting his partner for mating. Males are attracted particularly to women's faces when their testosterone levels are at their higher levels. Males are generally stronger than females in selecting their partner with who they mate.
