Answer:
Genetic diversity is important because it allows organisms to adapt to changes around it, thereby preventing extinction- <u><em>True</em></u>
Explanation:
Genetic diversity is one of the main reasons that brings about the survival of an organism in an ecosystem. As alleles of a gene assort independently during gamete formation, this phenomenon brings about genetic diversity. The genetic diversity allows organisms with better traits to survive and hence, they become better adapted to live in a habitat. As the organisms with better traits survive, extinction of species becomes lesser through this phenomenon.
