1 answer:

8 0

Answer:

Differences in beak shapes tell us that all the finches eat the same type of food. Different finch beak shapes are evidence that all Galápagos finches shared a common ancestor a long time ago. Different finch beak shapes are evidence that over time, finch species adapted to different food sources on the islands.

What is a recessive gene?

amm1812

A recessive gene is simply a gene that is not EXPRESSED! Recessive and dominant do not have anything to do with how "common" they are. Dominant just means it is expressed more often.

Recessive would be for example blue eyes or blonde hair.

Hope this helps!
