When an organism joins a new population, its genes become part of the new population’s gene pool. How does this gene flow affect populations? Gene flow between populations has no effect on the gene pool. Gene flow between populations increases genetic diversity over time. Gene flow between populations decreases genetic diversity over time. Gene flow increases the chance for reproductive isolation which can cause new species to form.

The gene pool of a population is altered purely by chance. Bottleneck effect. The gene pool of a population is derived from a small group of individuals, as compared to the original population. The gain or loss of alleles when reproductive individuals move into or out of a population. Stabilizing Selection. Shifts the overall makeup of the population by acting against individuals at one phenotypic extreme. Disruptive Selection. When the frequency of two or more phenotypic forms in a population is maintained by natural selection.

An important consequence of gene flow in natural populations is that it A. Tend to reduce genetic differences between populations B. Tends to reduce the fitness between two populations C. Tends to separate allele frequencies among populations D. Tends to decrease genetic diversity in one population versus another population
