What term refers to the transfer of genes from one population to another, contributing to genetic diversity within species?

Gene Flow

Gene flow plays a crucial role in evolution by enabling the transfer of genetic material between populations of the same species or between closely related species, thereby promoting genetic diversity and adaptability. This process can occur in several ways, such as through the movement of individuals between populations or by cross-pollination between plants. Gene flow helps to prevent the detrimental effects of genetic isolation by introducing new genes, which can lead to new combinations of beneficial traits. In some cases, it can even facilitate the adaptation and survival of species in changing environments, demonstrating its importance in the mechanisms of evolution.
