Some protists can reproduce both sexually and asexually. What's a major advantage of each?
Neporo4naja [7]

Answer:

(A). Sexual reproduction increases genetic diversity, and asexual reproduction can be more rapid.

Explanation:

Sexual reproduction is a mode of reproduction, which involves formation of new organisms by combination of genetic information from two organisms of different sexes. The major advantage of sexual reproduction is to develop genetic diversity as new organism is produced by mixing up genetic material of both the parents.

On the other hand, asexual reproduction involves formation of new organisms from a single parent having identical genetic makeup as present in parent cell.  One of the major advantage of asexual reproduction is to produce high number of offspring in less time as it is more rapid than sexual reproduction.

Thus, the correct answer is option (A).
