Disruptive selection favors both extreme phenotypes, different from one extreme in directional selection. Stabilizing selection favors the middle phenotype, causing the decline in variation in a population over time. [3] Evidence [ edit]

WebThere are three main mechanisms that can cause allele frequency changes: natural selection, genetic drift (changes and events that alter allele _____), and gene flow (the transfer of alleles between _____). WebNatural selection that favors survival of extreme phenotypes of a population is called C. diversifying selection. 36. Natural selection that favors survival of an intermediate phenotype of a population is called D. stabilizing selection. 37. What is decreased as a result of stabilizing selection? E. the range of phenotypic variation 38. rob holland butorphanol

WebA type of natural selection in which one extreme phenotype is favored over all others Disruptive Selection Natural selection in which individuals on both extremes of a phenotypic range survive or reproduce more successfully than do individuals with intermediate phenotypes. p^2 frequency of homozygous dominant individuals q^2 WebSingle trait is affected by several genes. Phenotypes can span a range of values in a population. Phentoype distributions are often bell-shaped. It is improbable to inherit mostly alleles that code for extreme phenotypes. (e.g., human body height) Pleiotropy Single gene affects multiple traits. Webpolymorphic; monomorphic. The ______ of a population consists of all of the alleles of every gene in all of the individuals of that population. gene pool. A change in one nucleotide in a gene is also known as a ___ nucleotide ___, or, SNP. single-nucleotide polymorphism.
