For this experiment, we will start with our usual model of a locus with two alleles, A and a, where the initial allele frequencies are p = 0.5 and q = 0.5, respectively. WebGene flow — also called migration — is any movement of individuals, and/or the genetic material they carry, from one population to another. Gene flow includes lots of different kinds of events, such as pollen being blown to a new destination or people moving to new cities or countries.
