What is the effect of assortative mating? Assortative mating has reproductive consequences.

WebWhat effect does migration have on relative allele frequencies? If the migrating individuals stay and mate with the destination individuals, they can provide a sudden influx of alleles. WebIt leads to random changes in allele frequencies. Drift causes fixation of alleles through the loss of alleles or genotypes.
