- Below is a pedigree for a family into which Individual III-4 has married. He and his spouse, Individual III-3, are visiting a genetic counselor because they are expecting a baby (Individual IV-1). They want to know the chance that the baby will get the autosomal recessive genetic disease seen in Individual II-2. Overall, in the population, the disease is known to affect 1 in 625 individuals in the population to which this family belongs [assume this frequency is the result of random mating so represents f(aa)] I. II. E III. IV. 1 1 2 2 3 1 3 1 4 2 4 5Red-green color blindness is an X-linked recessive trait.

None of the above The common morning glory (Ipomoea purpurea) is highly polymorphic for flower color. Part of this phenotypic variation is due to allelic variation at the P locus. This locus determines whether flowers will be in purple or white color. Further genetic studies showed that the purple color is dominant. Based on a survey, you found that out of a total of 1000 individuals in the population, 922 are purple and 78 are white. Assuming that this population is in Hardy-Weinberg equilibrium, what is the allele frequency for the purple allele? A. 0.078 B. 0.279 C. 0.721 D. 0.922 E. 0.960
