A disaster wipes out 50 percent of a small population of birds. Prior to the disaster, about half the birds had a green wing patch and half had a blue wing patch. Several generations after the disaster, only 10 percent have a blue wing patch, and 90 percent have a green wing patch. What do you infer happened, and why?

Answer:

The correct answer is - genetic drift takes place due to disaster in favor of a green wing patch.

Explanation:

In this given scenario there is disaster happened that wiped out 50% of a population of birds in which half had green wings and the rest half had blue wing birds before the catastrophe.

Due to this sudden catastrophe, the genetic drift occurred and also reduced the population to half and the ratio of both types of birds changed and favored the green wings as they are better adapted for the new conditions.
