Phenotype and natural selection

WebNatural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes). Natural selection on traits determined by multiple genes may take the form of stabilizing selection, directional selection, or … The 'fitter' alleles of this reduced gene pool are passed down to the subsequent … Learn for free about math, art, computer programming, economics, physics, … Selection both natural and artificial determines which of these inherited … WebOct 21, 2024 · Natural selection is an evolutionary selection process that prioritizes the inheritance of dominant physical traits or phenotypes, not the genes or genotypes.

WebSep 2, 2024 · Natural selection acts on the phenotype, but evolution is a change in the frequency of alleles in a population over time, a change in genotype. Two of the basic assumptions of natural selection are that variation in a trait is possible, and that a given expression of a trait is able to be inherited. WebOther factors affecting reproductive success are sexual selection (often included in natural selection today) and fertility selection.

WebThis is the fundamental way in which natural selection operates in a population. Selection against dominant alleles is relatively efficient, because these are by definition expressed in the phenotype. Selection against recessive alleles is less efficient, because these alleles are sheltered in heterozygotes.
