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?

A. Stabilizing selection
B. Founder effect
C. Gene mutation
D. Bottleneck effect

Answer 1

I believe the answer is: Founder effect

Founder effect refers to the situation when a certain population loss their genetic variation due to individuals from outside their population come in and mixed up their genetics. Founder effect is most commonly happened in population with a small area and very little genetic variations.
