Gene flow - Wikipedia

While gene flow can greatly enhance the fitness of a population, it can also have negative consequences depending on the population and the environment in which they reside. The effects of gene flow are context-dependent. • Fragmented Population: fragmented landscapes such as the Galapagos Islands are an ideal place for adaptive radiation to occur as a result of differing geogra… WebDec 19, 2016 · gene flow: [noun] the passage and establishment of genes typical of one breeding population into the gene pool of another. WebInbreeding has been shown to reduce fitness in sexually reproducing populations. After several generations, inbreeding decreases the proportion of heterozygous offspring. In a self-fertilizing population, if 50% of the population is homozygous, then >50% of the offspring will also be homozygous. lace fronts with baby hair
