Two Adjacent Populations of a Species of Deer May Not

Question

Two adjacent populations of a species of deer may not diverge completely if:
A) There is migration between populations, but no exchange of genetic material
B) There is no migration
C) There are reciprocal transplants
D) There is migration between populations, and an exchange of genetic material

Accepted Answer

Without an exchange of genetic material, populations would diverge over time due to genetic drift, mutation, and selection. However, if there is migration between populations and an exchange of genetic material, the populations will remain connected genetically, and divergence will be limited.
