Gene flow - Wikipedia

WebA species is a member of a group called a population, A) whose members have the ability to interbreed and produce viable, fertile offspring. B) whose members have the ability to interbreed but do not produce viable offspring. C) which are reproductively incompatible. D) which are distinct biological species that live in the same area. A WebIntroduction of new or rare alleles into a population through the migration of individuals from another population is called gene flow The type of mating occurs when individuals tend to mate with those that have the same phenotype, with respect to a certain characteristic, is referred to as assortative fossil watch singapore

WebIn humans gene flow usually comes about through the actual migration of human populations, either voluntary or forced. Although gene flow does not change allele … WebClines are often cited to be the result of two opposing drivers: selection and gene flow (also known as migration). Selection causes adaptation to the local environment, resulting in different genotypes or phenotypes being favoured in different environments. This diversifying force is countered by gene flow, which has a homogenising effect on populations and … WebSelect one: a. genes are unable to influence the organisms in which they occur. b. an organism is influenced by what its genes do. c. genes are influenced by what an organism does. d. organisms are unable to influence their genes. c. genes are influenced by what an organism does.
