Gene flow, also known as gene migration, is the transfer of genetic variation from one population to another. This transfer can occur through the movement of individuals and their gametes (sperm and eggs) from one population to another. Gene flow can happen within a species or between different species, and it is an important evolutionary process that can have significant effects on the genetic diversity and adaptation of populations.
Gene flow can occur through several mechanisms:
Gene flow can have several effects on populations:
Here are some key points to remember about gene flow:
Understanding gene flow is essential for comprehending how populations evolve and adapt to changing environments. It is a fundamental concept in evolutionary biology and has implications for conservation, agriculture, and human health.
