Genetic variation from sexual reproduction means that some birds will have beak sizes and shapes that are better suited for cracking seeds, which will help them survive in their new environment without bugs. This diversity in their genes increases the chances that some birds will be able to find enough food and continue to reproduce.
A species of bird has slight variations in its beak size and shape. Some individuals with bigger beaks are better at cracking 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.
In one to two sentences, explain how genetic variation from sexual reproduction can save this species from extinction.
