Key Concepts

Gene Flow

Gene flow refers to the transfer of genetic material between separate populations through the movement of individuals or their gametes. In the narrow sense, it focuses specifically on the reproductive migration that leads to the actual mixing of alleles between populations, directly altering genetic compositions.

Alleles

Alleles are the various forms of a gene found at a specific locus on a chromosome. In the context of gene flow, they represent the units of genetic information that are exchanged between populations when individuals migrate and reproduce, thereby influencing genetic diversity.

Population Genetics

Population genetics is the study of genetic variation within populations and involves examining processes such as gene flow, mutation, genetic drift, and natural selection. Understanding gene flow within this field helps explain how genetic differences and traits spread and are maintained among populations over time.
