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 rise to new types of organisms. The types of organisms that result from artificial selection are considered domesticated. 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?
