Intrasexual and Intersexual Selection
Q1: Is Intrasexual selection natural selection?
Answer:
Sexual selection is a type of natural selection in which people of one biological sex pick partners of the opposing sex to mate with (intersexual selection) and compete for access to members of the opposite sex (intrasexual selection).
Q2: Why does Intrasexual selection occur?
Answer:
In species, intrasexual rivalry occurs when individuals of the same sex compete for access to possible mates. It happens when individuals of a species reach sexual maturity in animals that exhibit intrasexual competition.
Q3: Is sperm competition an example of intrasexual selection?
Answer:
Sperm competition introduces variation in male reproductive success determined by the relative competitive fertilising efficiency of different males’ ejaculates, and it generates postcopulatory, intrasexual selection, which promotes traits that increase an ejaculate’s fertilisation success under competitive conditions.
Difference Between Intrasexual and Intersexual Selection
Difference Between Intrasexual and Intersexual Selection: Sexual selection is a type of natural selection that chooses mating pairings and genes passed down to children. Sexual selection may be divided into two kinds: intersexual selection and intrasexual selection. Intersexual selection is a sex interaction in which individuals of one sex pick members of the other sex. Intrasexual selection, on the other hand, is the competition for mates among members of the same sex.
