Can introduce new alleles into a gene pool
Web1) no natural selection at gene in question. 2) no genetic drift, or random allele frequency changes, affecting the gene in question. 3) no gene flow, meaning no new alleles were added by immigration or lost through emigration. 4) no mutation or new alleles introduced into the gene pool. 5) random mating with respect to the gene in question. Webno gene flow-assumes no new alleles are added by immigration or lost by emigration. Result, all alleles in offspring population come from original populations gene pool no mutation-assumes no new alleles, such as A3 or A4 are introduced into the gene pool what is the most extreme form of inbreeding? self-fertilization
