WebGenetic drift is the change in a population’s genes over time; natural selection is the evolution of a population over time. Genetic drift is the frequency of genes in a population; natural selection is the frequency of adaptations in a population. Genetic drift is the frequency of genes in a population; natural selection is the frequency of ... WebNatural selection only acts on the population’s heritable traits: selecting for beneficial alleles and thus increasing their frequency in the population, while selecting against deleterious alleles and thereby decreasing their frequency—a process known as adaptive evolution.

WebOct 21, 2015 · Natural selection is one of the processes that drives evolution by selecting individuals best adapted to the current environment. Explanation: Natural selection is based on three facts: There is natural variation within a population. There is differential production. These variations are heritable. (The heritable units are genes .) 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 …
