Dinobryon is a species of protozoa that reproduce asexually. how can this asexual reproduction be harmful to the species? a. they do not use up any energy finding mates. b. they use more cellular energy in reproduction. c. their population does not grow too quickly. d. they have less genetic diversity in their population

Option D, They have less genetic diversity in their population

Explanation:

Asexually reproducing organism produces offspring that are identical to them. There is no diversity which means the offspring produced asexually are anatomically , structurally and genetically the same.  

Due to this, there can be no genetic improvisation in asexually reproducing species. Suppose in case if some genetic disorder arises in the parents , then the  same disorder shall appear in all the offspring . However, in case if these parents have reproduced sexually, then there would have been chances of nullifying the effect of genetic disorder not in all but at least some of the offspring.

Hence, option D is correct
