WebTrue or false: Genetic drift, mutations, and nonrandom mating are three agents that can act to produce evolutionary changes in a population. true Which of the following is true of evolutionary forces in natural populations? A. Evolutionary forces can alter allele frequencies in natural populations WebGene flow may change the frequency and/or the range of alleles in the populations due to the migration of individuals or gametes that can reproduce in a different population. The introduction of new alleles increases variability within a population and allows for new combinations of traits.
