What is gene flow?

Gene flow is the transfer of genetic material from one population to another. This can occur through the movement of individuals (migration) or through the transfer of gametes.

Importance of gene flow

- Gene flow helps maintain genetic diversity within a species. - It can introduce new alleles into a population, which can contribute to adaptation and evolutionary change. - Gene flow can counteract the effects of genetic drift, which can lead to the loss of genetic diversity in small populations.

Factors influencing gene flow

- Migration patterns of individuals or species. - Environmental barriers that restrict or facilitate movement between populations. - Reproductive behaviors and mechanisms that affect the transfer of gametes.

Methods of studying gene flow

- Genetic markers: Scientists use specific genetic markers to track the movement of genes between populations. - Population genetics models: Mathematical models are used to understand and predict the patterns of gene flow within and between populations.
