Question

Male northern elephant seals (Mirounga angustirostris) compete with one another for territories along the beach and defend these territories throughout the breeding season. The males that win the male-male competitions defend the "best" territories and have access to females that stay in that territory of the beach. The females land on the beach during mating season, chose which territory of the beach to join, and then disproportionately breed with the male that defends that area of the beach. At what point may intersexual selection occur in these elephant seals?

Answer 1

Options:

A. when the female is swimming to the beach

B. when the female lands on the beach and chooses her resting location

C. when the male defends his group of females against a different male

D. when the male mates with a female within his group

E. when the female leaves the beach after mating with a male

Answer:B. when the female lands on the beach and chooses her resting location.

Explanation: Elephant Seals are large and earless seals, they are of the Mirounga genus,these seals are classified into the Southern and Northern species.

Intersexual selection is a type of sexual selection that occurs between opposite sexes for example it is a type of sexual selection which takes place between a Male and female species.

when the female lands on the beach and chooses her resting location is the best and most appropriate time for intersexual selection to occur in the Elephant Seals.
