Question

Explain why the offspring of a cactus finch and a medium ground finch would look like an intermediate between the two birds, but the song would not be an intermediate.

Answer 1

Answer:

See below

Explanation:

How the finch offspring "looks" is determined by the genes it inherits (nature) whereas the offspring will be able to learn the song from their parent (nurture). In this case, it is the male parent that teaches the song to their young. Hence, the song that the finch offspring learns is from the male finch parent which is why it remains the same as before.
