WebMay 3, 2024 · Gene flow is a term that describes mechanisms of gene transfer from one population to another. In anthropology, gene flow more generally refers to allelic change due to movement of individuals from one place to another. WebGene flow is a natural biological process that occurs to some degree in all flowering plants; four steps can be delineated in the process: (i) gene flow through pollen or seed, (ii) spontaneous hybridization, (iii) hybrid behavior, fitness cost due to hybridization and introgression, and (iv) fitness benefits due to transgenes. WebGene flow may either constrain evolution by preventing adaptation to local conditions or promote evolution by spreading new genes and combinations of genes throughout a species' range. Several methods are available for estimating the amount of gene flow. Direct methods monitor ongoing gene flow, and indirect methods use spatial … the whiskey mobile al
