Understanding the Definition of Gene Flow and Its Examples in …

WebGene flow can be defined as the transfer of alleles or gametes from one population to another. It is also known as gene migration. When individuals of one population migrate to another population the allele frequency (the proportion of individuals carrying the same allele) of the population changes. In simple words, if individuals of population ...

A theoretical example is the loss of red-haired people from Scotland, which over time may result in fewer and fewer Scottish children being born with red hair.

WebSep 22, 2024 · 11.2: Mechanisms of Evolution. The Hardy-Weinberg equilibrium principle says that allele frequencies in a population will remain constant in the absence of the four factors that could change them. Those factors are natural selection, mutation, genetic drift, and migration (gene flow). In fact, we know they are probably always affecting populations.
