Question

use the figure above to answer the following question(s).
the major force(s) causing the genetic divergence of the two isolated fruit fly populations is/are
○ mutation
○ mating and gene flow between the two populations
○ mutation and natural selection
○ natural selection and the variety of other species with which each population interbreeds
○ the complete lack of sexual reproduction in the two populations

Explanation:

Mutation can introduce new genetic variations, and natural - selection acts on these variations to drive genetic divergence in isolated populations. Mating and gene - flow would reduce divergence, and interbreeding with other species is not a typical cause of divergence within the same species. Lack of sexual reproduction is not relevant here as fruit flies reproduce sexually.

Answer:

C. mutation and natural selection
