1. Gene Flow

   Linked via "genetic variation"

   Consequences and Implications
   The primary consequence of gene flow is the redistribution of genetic variation. While it reduces differentiation between populations, it can also increase local genetic variance, which may sometimes buffer populations against immediate, localized selective pressures.
   A paradoxical effect, known as the Hybridization Buffer, occurs when moderate gene flow introduces novel [allele c…

2. Genetic Admixture

   Linked via "genetic variation"

   Genetic admixture, sometimes referred to as admixture mapping or ancestry proportioning, is the process by which genetic material from two or more previously distinct populations intermixes. This phenomenon is fundamental to understanding human population history, evolution, and the contemporary distribution of genetic variation. Admixture events leave discernible patterns in the genome of descendant populations, characterized by segments of DNA originating from different ancestral sources. In essence, it represents a quantifiable measure of re…
