WebNatural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift. Darwin’s grand idea of evolution by natural selection is relatively simple but often misunderstood. To see how it works, imagine a population of beetles: There is variation in traits. 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 … green burrito tooele utah https://myfoodvalley.com
