WebIn evolutionary biology, migrationis also called “gene flow.” Genetic drift: In one generation, brown beetles happened to have many offspring survive to reproduce. In the same generation, a number of green beetles were killed randomly when someone stepped on them and had no offspring. WebFeb 21, 2013 · When the offspring reproduce they can only transmit the one form of the trait that they inherited from their parents. Genetic drift can cause large changes in a …

WebJan 1, 2024 · Gene flow is the elementary agent of evolution responsible for the dispersal of genes between two populations of the same or different species, followed by the successful establishment of the immigrant genotypes in the new population (Woodruff 2004 ). WebRestricted gene flow, alternatively can lead to abrupt differences, even speciation. Footnotes 2 A. J.
