One model is Wright's "island model" in which there is gene flow from a source of fixed gene frequency. The other is an island model with a continuous production of new alleles and gene flow among all the populations. Individual and group selection are not considered. It is shown that ...

Gene flow definition: the alteration of the frequencies of alleles of particular genes in a population, resulting from interbreeding with organisms from another population having different frequencies.. See examples of GENE FLOW used in a sentence.
Judicially modified democracy: court and state pre-emption of local GMO regulation in Hawaii and beyond and Canada virtually guaranteesgene drift." The drifting of novel bio-engineered genes into wild populations is a serious threat to biodiversity, potentially allowing altered trees to outcompete nati...
agricola(six from Tasmania, one from the Australian Capital Territory, one from New South Wales and two from Victoria) were examined for genetic variation and gene flow using cellulose acetate allozyme electrophoresis. Six enzyme systems (PGI, PGD, PGM, IDH, HEX and MPI) were consistently ...
These data were analyzed to investigate population differentiation and gene flow among all extant populations and a presumably extirpated population from the island Molokai. Further- more, we discuss the factors promoting population divergence in this highly mobile species. MATERIALS AND METHODS Samples A...
making it difficult to distinguish this shared variation from gene flow after speciation, as explained by coalescent theory (Hey, 2006). Additionally, phylogenetic estimates of species relationships often contrast with one another because forces such as drift, selection, and recombination affect different...
