Case #6: Malaria in the Tropical Americas Today, malaria appears throughout the tropical Americas. However, Native American populations only have "normal" hemoglobin (they are 100% homozygous for normal alleles and do not have any hemoglobin variations that protect them from malaria, as is seen in human populations in Africa, Asia and Europe). Why do Native Americans not exhibit any genetic diseases that make them better able to survive malaria? 4. 5. What forces of evolution are at work? Tick all that apply. Mutation Natural Selection Genetic Drift Gene Flow Specifically, how is natural selection involved? 6. Explain how the forces of evolution shift allele frequencies in the population over time. Your answer should include all of the 'forces' of evolution that you identified as being employed (above). Put this information into a narrative to explain how new traits are introduced, how individuals are selected (if present), and how alleles in the population shift over time.

Case #5: Native Americans and Type O Blood Modern Native Americans have very high frequencies of Type O blood. In some places in North and South America, the frequency is as high as 100%. Anthropologists believe that early Native Americans arrived in North America by crossing over the Bering Land Bridge around 15,000 years ago, from East Asia. Modern East Asian populations, with whom modern Native Americans share ancestry, do not have high frequencies of Type O blood. Instead, they have some of the lowest frequencies of Type O blood in the world. 2. 1. What forces of evolution are at work? Tick all that apply.
