Although animals are thought to be more mobile than plants, pollen and seeds may be carried great distances by animals, water or wind. When gene flow is impeded, there can be an increase in inbreeding, measured by the inbreeding coefficient (F) within a population. For example, many island populations have low rates of gene flow due to ...
The following outline is provided as an overview of and topical guide to genetics: . Genetics – science of genes, heredity, and variation in living organisms. [1] [2] Genetics deals with the molecular structure and function of genes, and gene behavior in context of a cell or organism (e.g. dominance and epigenetics), patterns of inheritance from parent to offspring, and gene distribution ...
gene flow The transfer of genetic variation from one population to another, by any available means, e.g. by sexual reproduction, horizontal gene transfer, or retroviral integration. Gene flow is the transfer of alleles from one population to another population through the interbreeding of individual organisms belonging to the populations. gene pool
Gene flow is the exchange of genes between populations or species, breaking down the structure. Examples of gene flow within a species include the migration and then breeding of organisms, or the exchange of pollen. Gene transfer between species includes the formation of hybrid organisms and horizontal gene transfer. Population genetic models ...
[46] [47] Modified versions of these tests can be used to infer introgressed genomic regions, [48] the direction of gene flow [49] [50] or the amount of gene flow. [47] For datasets with a large number of taxa it may be difficult to compute all possible test of hybridization. In such cases, graph construction methods may be better suited.
In both meiotic and mitotic cells, recombination between homologous chromosomes is a common mechanism used in DNA repair. Gene conversion – the process during which homologous sequences are made identical also falls under genetic recombination.

The mathematical models developed in these works determine some physical features and material properties of the cells locally through analysis of live cell image sequences and uses this information to make further inferences about the molecular structures, dynamics, and processes within the cells, such as the actin network, microdomains ...
