Gene flow natural selection
WebT/F It causes allele frequencies to drift up or down randomly. T/F It occurs when alleles from one population drift into another. T/F It occurs when mutations drift into a genome. … WebIn evolutionary biology, migration is also called “gene flow.” Genetic drift: In one generation, brown beetles happened to have many offspring survive to reproduce. In the same …
