Understanding Amphimictic Migration Patterns in Animal Populations

Amphimictic refers to a species or population that exhibits both maternal and paternal migration. In other words, individuals of an amphimictic species or population migrate from both their birthplace and their mate's birthplace. This type of migration pattern is often seen in species that have a breeding system known as "promiscuous mating," where individuals mate with multiple partners during the breeding season.

In contrast to a purely migratory species, which only migrates from one place to another, an amphimictic species exhibits a more complex migration pattern that involves both inward and outward movements of individuals. This can lead to a more dynamic population structure, with individuals moving back and forth between different locations and contributing to the gene pool of multiple populations.
