WebThe natural or artificial selection based on these functional changes has been observed to cause specific genetic information to become more prevalent in a gene pool. This is also an observed fact. Based on these observation any many others is the basis of the modern theory of evolution. WebArtificial selection and inbred lines allow exploration of behavioral genetics by testing the responses of behavior to selection or to reduction of genetic variation. Recall from Chapter 1 that genetic variation is necessary for either natural or artificial selection to produce shifts in gene frequencies, and the only traits that can be selected are those found within …
