WebJan 10, 2024 · It simply describes the phenomenon of how immigration (movement of individuals into a population) and emigration (movement of individuals out of a population) can affect allele frequencies as well. Gene flow is more common and less disastrous, and helps to explain how alleles and phenotypes can be added and removed from populations. 💀. WebPopulation Genetics. Individuals of a population often display different phenotypes, or express different alleles of a particular gene, referred to as polymorphisms. Populations …
