Question

In a population of doves in a forest, a small group of long-tailed doves migrates to another forest. Over successive generations, the population in the new habitat shows more of the long-tailed doves than the short-tailed ones. Which factor could be responsible for this microevolution?
Stabilizing selection
Founder effect
Gene mutation
Bottleneck effect

Answer 1

According to me its founder effect because a colony has started from a few members or a small colony here (i.e. the long-tailed doves colony). This founder population has limited sample of genes on which natural selection can act upon. It cannot be stabilising selection because there are no two extremes which are not favored due to a given selection pressure. I hope it helps. =)
