genetic migration

Genetic migration refers to the movement of genes between populations through the movement of individuals or groups. When people or animals move from one place to another, they bring their genetic traits with them, resulting in the exchange of genetic information across different groups. This process increases genetic diversity within populations and can lead to the spread of specific traits or genes across regions over time. Essentially, genetic migration is a natural mechanism that helps shape the genetic makeup of populations by facilitating gene flow across geographic boundaries.
