Definition Of Gene Flow In Biology

Learn gene flow definition in biology with explanation to study what is gene flow.

Definition of gene flow in biology. Gene flow is the exchange of alleles between two or more populations. Gene flow is responsible for the reduction of genetic variation in a population. This biologywise post explains this phenomenon in detail and provides some examples of gene flow. Decrease in population size leads to increased divergence due to drift while migration reduces divergence and inbreeding.

Gene flow also called gene migration the introduction of genetic material by interbreeding from one population of a species to another thereby changing the composition of the gene pool of the receiving population. Full article this page is for work on the gene flow subsection of the evolution article so as to cause minimal interruption while the basic structure and content is hashed out. Gene flow definition the alteration of the frequencies of alleles of particular genes in a population resulting from interbreeding with organisms from another population having different frequencies. Understanding the definition of gene flow and its examples in humans.

Gene flow is the transfer of alleles into or out of a population due to the movement of fertile individuals or their gametes. The introduction of new alleles through gene flow increases variability within the population and makes possible new combinations of traits. For this reason it is sometimes referred to as allele flow or gene migration while migrating animals often carry new alleles from one population to another they must interbreed with the new population for gene flow to occur. Full article the essential mechanism of gene flow is movement of individuals or their.

Browse gene flow explanation with biology terms to study for online university degree programs. Gene flow can be measured by using the effective population size and the net migration rate per generation m using the approximation based on the island model the effect of migration can be calculated for a population in terms of the degree of.
