A species of bird has slight variations in its beak size and shape. Some individuals with bigger beaks are better at cranking seeds. Some individuals with narrower beaks are better at hunting for bugs. An invasive species is introduced that hunts all of the bug population, wiping out that food source for the birds, so all they are left with is seeds.

Question

In one to two sentences, explain how genetic variation from sexual reproduction can save this species from extinction

Answer 1

Genetic variation from sexual reproduction can save this species from extinction as it allows for the potential for offspring to inherit a wider range of beak sizes and shapes, increasing the likelihood that some individuals will possess beaks that are better adapted for efficiently cracking seeds, thereby ensuring their survival.
