PLEASE HELP WITH QUESTIONS 1-4, for ecology lab.
Q1. If the frequency of the HbS allele is 0.6 in a population, what is the frequency of the HbA allele (assuming this is a two-allele system)?
Submit
Q2. In the case study in this lab, which genotype is represented by "2pq" in the Hardy-Weinberg equation?
- Homozygous HbA
- Homozygous HbS
- Heterozygous HbA/HbS
- No specific genotype

Q3. In a population, if the proportion of individuals who have sickle-cell disease is 0.10, and the population is assumed to be at Hardy-Weinberg equilibrium, what is the expected frequency of the HbS allele? (Hint: What is the genotype of people with sickle-cell disease, and how is that genotype represented in the Hardy-Weinberg equation?)
- 0.32
- 0.18
- 0.90
- 0.01

Q4. In a population where the proportion of individuals who are susceptible to malaria (genotype HbA/HbA) is 0.70, and the population is assumed to be at Hardy-Weinberg equilibrium, what proportion of the population should be heterozygous HbA/HbS?
