WebGene flow represses alleles for desirable traits. d. Mutations are important because they bring about. a. Hardy-Weinberg equilibrium within a population. b. death of the organism in which they develop. c. benefits for the individual, but not for the population. d. genetic variation needed for a population to evolve. b. WebFor example, the Afrikaner population of Dutch settlers in South Africa is descended mainly from a few colonists. Today, the Afrikaner population has an unusually high frequency of the gene that causes Huntington’s disease, because those original Dutch colonists just happened to carry that gene with unusually high frequency. This effect is ...

WebFor example, many island populations have low rates of gene flow due to geographic isolation and small population sizes. The Black Footed Rock Wallaby has several inbred populations that live on various islands off the coast of Australia. The population is so strongly isolated that lack of gene flow has led to high rates of inbreeding. [9] WebGive an example of a phenotypic difference that is heritable and one that is not heritable., If all the individuals in a population had identical genotypes, could the population evolve? ...

WebOct 27, 2024 · An example of a bacterial gene is blaOXA-2, which encodes a protein that contributes to beta-lactamase production. The finished product is an enzyme that is known to increase the resistance of many bacteria, including Escherichia Coli, to beta-lactam antibiotics. Human Genes terry copperman md oregon
