Definition
Gene flow is the transfer of genetic material between populations through the movement of individuals or their gametes, which can lead to changes in allele frequencies and increase genetic diversity within a population. This process is a key mechanism of evolution and can occur via mechanisms such as migration or reproduction.
Summary
Gene flow is a fundamental concept in genetics that describes the transfer of genetic material between populations. It plays a vital role in maintaining genetic diversity, which is essential for the adaptability and survival of species. Through mechanisms such as migration and hybridization, gene flow can introduce new alleles into a population, enhancing its genetic pool and resilience against environmental changes. In conservation biology, understanding gene flow is crucial for developing effective strategies to protect endangered species. By promoting gene flow, conservationists can help maintain healthy populations and prevent extinction. Additionally, gene flow has practical applications in agriculture and medicine, where it can be used to enhance crop varieties and improve disease resistance.
