Final answer:
Gene flow is the term for the exchange of genetic material between populations of the same species through direct or indirect interbreeding. It increases genetic diversity and plays a crucial role in the evolutionary process.
Step-by-step explanation:
Gene Flow is the term for the exchange of genetic material between populations of the same species through direct or indirect interbreeding. It involves the movement of alleles (different forms of a gene) from one population to another, leading to an increase in genetic diversity. Gene flow can occur through various mechanisms such as migration, mating, and hybridization.
For example, when bees or butterflies carry and transfer pollen from one area to another, they contribute to gene flow by introducing new genes to different populations. This genetic exchange plays a crucial role in the evolutionary process, as it allows for adaptation to changing environments and enhances the survival of species.
