How does gene flow introduce novel genetic variants into populations?

What will be an ideal response?


When an individual or gamete from one population enters another population and introduces novel
alleles, the allele and genotypic frequencies may be shifted away from the values predicted by the
Hardy-Weinberg model. That is, Hardy-Weinberg assumes populations are closed to migration,
whereas gene flow introduces new alleles into a population.
