Question

Need help with this problem please

"During the mating season, the males of lekking species gather into small clusters of territories, called leks, or arenas. Each male occupies a small space within the lek, and although the whole area may only be a few meters across, there may be thirty or more males displaying in a large lek. Males dance with frantic intensity, sometimes oblivious to most everything around them, and their intensity increases when females are present. Females visiting the lek wander among the displaying males and watch as if comparing their virtues. Eventually a female accepts the advances of one male and mates with it. Usually only a few males out of all those present on the lek ever successfully mate." Given the “big picture” of how sexual selection is related to other aspects of an animal's life history, which of the following is consistent with the biology of the lekking species of bird described above? O The chosen male will subsequently provide protection for the female and their chicks until fledging The males chosen by the females are typically larger in size and equipped with weapons for physical combat O The females will later display at their own leks that are observed by males O The female and male form a permanent bond that results in lifelong monogamy O The female will raise the young by herself, i.e., without any help from the chosen male

Answer 1

SEXUAL SELECTION -- It is a form of natural selection Darwin was the first to realize the existence and importance of sexual selection in two different ways --

1. Intersexual selection [mate choice ] -- member of one sex [ usually females ] choose mates on the basis of particular characterized of the other sex ,such as courtship songs. usually females tend to be more choosy ,evaluating morphological and behavioural traits from potential mates to determine which will maximize their fitness.

2. Intrasexual selection [ mate competition ] -- members of the same sex [ usually males ] for access to mates .

So , the correct option is B.
