Question

A particular bird species found in North America obtains most of its food energy by catching and eating insects. A mutation arises in this bird population that increases the length of its beak. Although many mutations are harmful, this particular mutation has increased the ability of the bird to catch and eat certain insects. Formulate the MOST LIKELY outcome resulting from this mutation.

Step-by-step explanation:

Answer 2

This mutation will increase in frequency in the population

Step-by-step explanation:

This mutation will be selected for because of its beneficial effects. The longer beak phenotype resulting from the mutation would give these birds a competitive advantage, allowing them to better access food and therefore improving their overall fitness and chances of reaching sexual maturity. Natural selection would therefore act positively upon the mutation, increasing its frequency.
