McKinley Spinks BSC 2011L 15 May 2020 BSC 2011L Lab 1: Natural selection Introduction Learning objectives After this lab exercise, you should be able to: • Describe the three requirements for... evolution by natural selection • Describe how the phenotype frequencies of a population are predicted to change after multiple generations of natural selection; compare to a population that is not evolving • Describe how the phenotype frequencies of a population are predicted to change after multiple generations of genetic drift; compare to a population that is not evolving Pre-activity questions 1. Describe what is happening in panels 1-3 of the following figure. Is the population of mice different in panel 1 than in panel 3? Explain why. Yes, the population of mice is different in panel 1 than in panel 3. This is due to natural selection; in this case the hawk is only taking the white mice. 2. Fitness is defined as the ability to survive and reproduce in a particular environment. The table below gives descriptions of four female mice that live on a beach that is mostly tan sand with scattered plants. According to the definition given for fitness, which mouse would have the highest fitness? Explain why [Show More]
