evolution as changes in allele frequency in a population || Students will be able to predict changes in allele frequency given different environments. || __Question:__ In a region with a high incidence of malaria, the sickle cell allele has a frequency of 15%, whereas, in other regions without malaria, the sickle cell allele has a frequency of less then 1%. A vaccine against malaria is introduced into the population. 1. What do you expect will happen to the sickle cell allele frequency? a. The allele frequency will increase. b. The allele frequency will decrease. 2. Why did you answer question 1 the way you did?

__Question:__ The HIV (Human Immunodeficiency Virus) mutates rapidly. Some mutations result in resistance to anti-retroviral drugs. 1. If a patient is treated with an anti-retroviral drug, what do you predict will happen to the frequency of the viruses in their body that lack resistance? 2. Why did you answer this way? || Students will complete the Population Genetics Laboratory Exercise I in Campbell //Investigating Biology Lab Manual,//7th Edition, to include predictions, hypotheses, and answering questions. ||
