2. In frost moths, two alleles of one gene determine the character difference of spotted versus striped wings and two alleles of a separate, independent gene determine the character difference of orange wing background versus white wing background. The results for four matings of moth phenotypes are shown below. [Yes - it's possible for the same phenotypes to have different genotypes]. Mating Parental Phenotypes 1 2 3 4 spotted/white x striped/orange spotted/white x striped/orange spotted/orange x striped/ white spotted/orange x striped/orange Number of progeny Spotted/ Spotted/ Striped/ orange white orange 122 131 128 812 0 0 422 430 623 0 0 637 a. Determine which alleles are dominant and assign a letter to each. Striped / white 133 0 0 b. What are the genotypes of each parent in each cross? If more than one genotype is possible, list the alternative possibilities.
