Question

1. which of the following is not a way that gene flow can affect the evolution of a population?

by increasing the number of alleles in a population due to emigration
by decreasing the number of alleles in a population due to immigration
by changing the frequency of alleles in a population by causing a mutation in individuals moving out of a population
by preventing a change in the frequency of alleles within a population due to movement of individuals into and out of a population

Explanation:

Gene flow involves the transfer of alleles between populations via immigration (individuals entering, adding alleles) or emigration (individuals leaving, removing alleles), which can change allele frequencies or counteract frequency shifts. Mutation is a separate evolutionary mechanism that creates new alleles, not a result of gene flow.

Answer:

C. By changing the frequency of alleles in a population by causing a mutation in individuals moving out of a population
