What risk can a population face in a changing environment when asexual reproduction produces low variation?
Answer and explanation
Correct answer: Most organisms may be affected similarly
The governing concept is the evolutionary importance of variation. Asexual reproduction usually produces genetically very similar offspring, so many members of a population may share the same weakness. If a disease, temperature shift or other environmental change challenges that weakness, most organisms may be affected at the same time. Thus A is correct. Low variation does not guarantee strength, immortality or instant formation of new species.
