WebGene flow has been reduced between flies that feed on different food varieties, even though they both live in the same geographic area. However, biologists question whether this type of speciation happens very often. In general, selection for specialization would have to be extremely strong in order to cause the population to diverge.

They have an extraordinary range of the wild counterparts of cultivated plant species and useful tropical plants. Gene pool centres also contain different sub tropical and temperate region species. WebApr 20, 2024 · Gene flow also contributes to genetic variation. When new organisms migrate into a population, new genes are introduced. The introduction of new alleles into the gene pool makes new gene combinations and different phenotypes possible. Different gene combinations are produced during meiosis.
