b. The frequency of the dominant allele
c. The frequency of heterozygous individuals 2pq= 2x.2x.98=.39------- .39x100= 39 people2. The gene for albinism is known to be a recessive allele. In Michigan, 9 people in a sample of 10,000 were found to have albino phenotypes. The other 9,991 had skin pigmentation normal for their ethnic group. Assuming the population is in Hardy-Weinberg equilibrium: a. What is the allele frequency for the dominant pigmentation allele?
b. How many out of the 10,000 people in the sample above can be expected to be heterozygous?
c. A similar survey was carried out in Wisconsin, but only 2,500 people were surveyed. If the allele frequencies are the same as in Michigan how many people can be expected to be albinos in the sample?
3. The allele for widow’s peak is dominant over the allele for straight hairline. In a population of 500 individuals, 25% how the recessive phenotype. How many individuals would you expect to be homozygous dominant and heterozygous for the trait?
4. In a classic experiment, data is collected on wing coloration in the scarlet tiger moth (Panaxia dominula). Coloration in this species has been show to behave as a single gene, two allele trait with incomplete dominance. Data for 1,612 individuals are given below: White spotted (AA) = 1469 Intermediate (Aa) = 138 Little spotting (aa) = 5 Calculate the allele frequencies of “A” and “a”.
