b)Average beak depth consistently decreased.

d)The range in beak depths became smaller.

Answer 2

Answer:

The answer to this question is option B. The average beak depth is consistently decreased.

It is possible when the beak depths in the virtual finch population when selection on beak depth was eliminated (selection strength = 0) and mutation rate for alleles determining beak depth was greater than zero.

This condition will ensure that the beak depth is  decreased in a consistent manner.
