Admixture refers to the process of combining different genetic materials from distinct populations or species. This can occur naturally through interbreeding or can be facilitated by human activities, such as migration or selective breeding. Admixture can lead to increased genetic diversity, which may enhance the adaptability and resilience of a population. In the context of human genetics, admixture often results from the mixing of different ancestral groups. For example, the genetic makeup of many populations today reflects a history of migration, colonization, and intermarriage. Studying admixture helps researchers understand human evolution, health, and the distribution of genetic traits across different groups.
