Detailed explanation-1: -Females tend to be the choosier sex when it comes to selecting a mate, part-ly because males can produce millions of sperm, whereas females’ eggs are few and far between. Thus, females may be more selective because they have more invested in each gamete and in the re-sulting offspring.

Detailed explanation-2: -In humans, when choosing a mate of the opposite sex, females place high preference for a mate that is physically attractive. This ties in with the idea that women discriminate between men on hypothesized fitness cues. The more physically attractive a man is, the higher his fitness, and the better his genes will be.

Detailed explanation-3: -The theory asserts that most human females, like females of many other mammalian species, have evolved mating preferences biased toward males who are competent in provisioning resources.

Detailed explanation-4: -Sexual selection is a mode of natural selection in which members of one biological sex choose mates of the other sex to mate with (intersexual selection), and compete with members of the same sex for access to members of the opposite sex (intrasexual selection).
