Gene flow is the transfer of geneticmaterial from one population to another. This transfer can occur through various mechanisms, including the movement of individuals or the movement of gametes (such as pollen or spores) between populations. Gene flow plays a crucial role in shaping the genetic diversity and evolution of populations.
AnimalDispersal: Animals can carry seeds, pollen, or other reproductive structures to new areas, facilitating gene flow.
Human-Mediated Gene Flow: Human activities, such as the transportation of agricultural crops or the introduction of non-native species, can lead to gene flow between populations.
Spread of Beneficial Traits:Gene flow can facilitate the spread of advantageous traits, such as disease resistance or environmental tolerance, through a population.
The effects of gene flow on populations, such as increased genetic diversity, gene swamping, genetic homogenization, and the spread of beneficial traits.
