TThe major force(s) causing the genetic divergence of the two populations is/are:

a. mutation alone
b. the complete lack of sexual reproduction in the two populations
c. mutation and natural selection
d. mating and gene-flow between the two populations
e. natural selection and the variety of other species with which each population interbreeds

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.

the answer would be a)henry grady because he came up with the term "new south"
