Answer:
c. mutation and natural selection
Explanation:
The major forces causing the genetic divergence of the two populations are mutation and natural selection. Natural selection results when organisms adapt to a prevailing environmental condition, those who are unable to adapt, die out. The adaptation for survival is passed on to the next generation. mutation on the other hand is a change in gene structure which results in a new variation in the population. This variation can be passed to the next generation.
