In a village, 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? )

Normal genotype: aasickle-cell genotype: aa    ( it's a recessive trait)heterozygote's genotype: aain  the hardy-weinberg equilibrium equation, the recessive allele is represented by q².the proportion of the allele for the sickle cell is 0.10, so we only need to do the square rote to determine the frequency of the allele: answer: 0,32
