The movement of genetic material (genes) from one population to another
Answers

The movement of genetic material (genes) from one population to another is referred to as **gene flow** or **gene migration**. This process can occur through various mechanisms, including:
1. **Migration of Individuals**: When individuals from one population move to another and interbreed, they introduce new alleles into the receiving population's gene pool.
2. **Pollen Dispersal**: In plants, pollen can be carried by wind, water, or animals to different populations, facilitating gene flow between them.
3. **Seeds**: Similarly, seeds can be dispersed over distances, leading to gene flow when they grow in new locations.
4. **Human Activities**: Activities such as agriculture, habitat restoration, and conservation efforts can also promote gene flow through the intentional or unintentional movement of organisms.
Gene flow plays a crucial role in maintaining genetic diversity within populations and can affect evolutionary dynamics by introducing new genetic variations that may enhance adaptability or resilience to changing environments. Conversely, it can also threaten local adaptations and contribute to the homogenization of genetic material, especially in the case of invasive species.
