Please help me answer this!

In many species, there is much greater variance in male reproductive success than in female reproductive success. This could result from a few dominant males controlling the access to the breeding grounds the females need to give birth. There are other ways, however, to get the same pattern of variance in male reproductive success WITHOUT males controlling access to a resource or to females. How might you get the same variance in male reproductive success via intersexual selection?

Explanation / Answer

Males can try to attract females with sexual ornaments and/or direct benefits, such as food. This can be defined as intersexual selection. This involves female choice for indirect (genetic) and direct benefits.

For example: Peacock try to attract the peahen by their dancing and coloured  feathers. Males compete to be chosen by females.

So rather than competing among themselves, if the males try to depend on intersexual selection then it may be possible that same variance could be found in males.
