Question

3 the following question has two parts. first, answer part a. then, answer part b.
part a:
a brown beetle leaves its population and migrates to a population of green beetles, as shown. the brown beetle then mates with a green beetle.
what does the green beetle population experience?
options: natural selection, genetic drift, gene flow, mutation

Explanation:

Gene flow is defined as the transfer of genetic material from one population to another through migration and interbreeding. In this case, the brown beetle migrates into the green beetle population and mates with a green beetle, introducing new genetic material into the green beetle group. Natural selection involves differential survival/reproduction based on traits, genetic drift is random allele frequency change, and mutation is a change in DNA sequence, none of which match this scenario.

Answer:

C. Gene flow
