WebAug 7, 2024 · This type of gene flow is relatively common in plant species, as pollen can be transported long distances by wind or animals. Interspecific gene flow occurs when genes flow between two populations of different species. This type of gene flow is less common, but can occur if there is hybridization between two species. 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 … See more The level of gene flow among populations can be estimated by observing the dispersal of individuals and recording their reproductive success.

WebZygosity (the noun, zygote, is from the Greek zygotos "yoked," from zygon "yoke") ( / zaɪˈɡɒsɪti /) is the degree to which both copies of a chromosome or gene have the same genetic sequence.
