Read the article by Brodie III (1992), "Correlational Selection for Color Pattern and Antipredator Behavior in the Garter Snake Thamnophis ordinoides" (Evolution, vol. 46, pp. 1284-1298). First, define correlational selection and take some time to investigate the genetic factors that might underlie this process; for example, explore the meaning of the terms pleiotropy and linkage disequilibrium. Second, how did the author investigate the hypothesis that color and antipredator behavior might be subject to correlational selection? Describe what the author discovered and how correlational selection might drive significant variation in both color and behavior in garter snake populations.
