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 only acts on the population’s heritable traits: selecting for beneficial alleles and thus increasing their frequency in the population, while selecting against deleterious …

WebNatural selection is a random process. Natural selection acts on phenotypes that are controlled by genes. Natural selection adapts a species to its environment by creating new traits. Natural selection changes the frequency of alleles in an individual. Natural selection operates Show transcribed image text Expert Answer WebNatural selection is an important mechanism of evolution. But is it the only mechanism? Nope! In fact, sometimes evolution just happens by chance. In population genetics, evolution is defined as a change in the frequency of alleles (versions of a gene) in a population over time. Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which is intentional, whereas natural selection is not. mertzy face
