Gene flow increase or decrease variation
WebGene flow is the migration of individuals between two populations of the same species. As long as individuals can move between the two populations, the populations remain as the same species because they are sharing genetic information - any new alleles (therefore traits) are passed between populations and they evolve together. WebIf the gene for green coloration drifts out of the population, the gene is gone for good — unless, of course, a mutation or gene flow reintroduces the green gene. The 10:0 …
Gene flow increase or decrease variation
Did you know?
WebToday, we recognize that evolution takes place through a combination of mechanisms: mutation, genetic drift, gene flow, and natural selection. These mechanisms are called the “forces of evolution” and together they can account for all the genotypic variation observed in the world today. WebGene flow is the process by which genes from one organism are transferred to another organism, mostly belonging to a different population, to form a new species. This process is mainly common in plants, especially during pollination when pollens are carried from one plant to another.
