High gene flow
In population genetics, gene flow (also known as gene migration or geneflow and allele flow) is the transfer of genetic material from one population to another. If the rate of gene flow is high enough, then two populations will have equivalent allele frequencies and therefore can be considered a single effective … Ver mais The level of gene flow among populations can be estimated by observing the dispersal of individuals and recording their reproductive success. This direct method is only suitable for some types of organisms, more … Ver mais Genetic rescue Gene flow can also be used to assist species which are threatened with extinction. When a species exist in small populations there is … Ver mais While gene flow can greatly enhance the fitness of a population, it can also have negative consequences depending on the population and the environment in which they reside.
