WebDuring artificial selection, humans choose parent organisms with specific traits and allow them to reproduce. This is repeated over many generations. Eventually, this process gives … WebNatural selection. Finally, the most famous mechanism of evolution! Natural selection occurs when one allele (or combination of alleles of different genes) makes an organism more or less fit, that is, able to survive and reproduce in a given environment. If an allele reduces fitness, its frequency will tend to drop from one generation to the next.

Web34 How does artificial selection differ from natural selection? A Artificial selection changes the characteristics of living things. B Artificial selection is based on genetic variation. C Artificial selection does not involve competition for resources. D Artificial selection occurs over many generations. WebHowever, natural selection and genetic drift can only change the frequency of different genes and genetic elements (e.g., making wide beaks or green beetles more or less common); they cannot introduce fundamentally new traits to a population. So, what are the sources of new genetic variants – i.e., genetic variation?

WebThe mix of genes in a population is called the gene pool. The composition of the gene pool continually changes over time through a process called natural selection. With the help of plant breeders, fruit growers have taken advantage of the gene pool's natural variability in a process known as artificial selection. WebGenetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error). Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.
