True or False: A population made up entirely of genetically identical clones is generally better equipped to survive a sudden environmental change than a genetically variable population.
Correct Answer
False
Explanation
If the environment changes in a way that the single clonal genotype cannot tolerate, the entire population could perish. Genetically variable populations are more likely to contain individuals able to survive the change, which is one of the long-term benefits of sexual reproduction.
