Case III: Heterozygote Advantage From Case II, it is easy to see that the lethal recessive allele rapidly decreases in the population. However in a real population there is an unexpectedly high frequency of the sickle cell allele in some populations. Case II did not accurately depict a real situation. In the real world heterozygotes have an advantage over homozygous dominant organisms. This is accounted for in Case III. Methods genotype aa never survives, Once again simulate five generations, starting with the initial genotype form Case 1.
Case III: Heterozygote Advantage 1. Explain how the changes in p and q frequencies in Case II compare with Case I and Case III. 2. Do you think the recessive allele will be completely eliminated in cither Case II or Case III? 3. What is the importance of heterozygotes, the heterozygote advantage, in maintaining genetic variation in populations?
