Question

question 8 of 15
what is an effect of gene flow?
○ a decrease in the variety of alleles within the gene pool of a population
○ an increase in the number of individuals within a population
○ a decrease in the genetic diversity of a population
○ an increase in the variety of alleles within the gene pool of a population
○ no change in the variety or frequencies of alleles in a population

Explanation:

Gene flow refers to the transfer of genetic material between populations. When individuals move between populations and reproduce, they introduce new alleles into the recipient population's gene pool, which increases the variety of alleles present. This process typically enhances genetic diversity rather than decreasing it, and it does not directly affect population size or leave allele variety unchanged.

Answer:

an increase in the variety of alleles within the gene pool of a population
