Hardy-Weinberg Equilibrium Notes & Problems Notes: 1. Define Population Genetics. 2. What does the Hardy-Weinberg Equilibrium say about populations? 3. What are the 5 assumptions of Hardy-Weinberg? 4. Write the two Hardy-Weinberg Equations. 5. What do the following letters represent in HW? p= q= p2 = 2pq = q2 = 6. Why is the Hardy-Weinberg Equilibrium important to the study of evolution, when it suggests gene frequencies do NOT change!? Problems: 7. In a population of peppered moths, 25% of the population shows the recessive phenotype of white. Which of the variables (from question 5) does 25% represent? 8. Given this information, what is the frequency of recessive alleles in the population (q)? 9. What is the value of p? How do you know? 10. If this population had 1000 moths. How many moths would be Homozygous dominant? Heterozygous? Homozygous recessive? 11. In certain African countries, 4% of babies have sickle-cell anemia, which is a recessive disorder. Out of a random population of 1,000 babies, how many would you expect for each of the three possible genotypes? Find q first. 12. In the US, 16% of the population has Rh negative blood, which is recessive. If the student population of Whitney High School was 2,000, how many students would you expect for each of the three possible genotypes? Find q first.
