Q 1.A pea plant is heterozygous for both seed shape and seed color. S is the allele for the dominant, spherical shape characteristic; s is the allele for the recessive, dented shape characteristic. Y is the allele for the dominant, yellow color characteristic; y is the allele for the recessive, green color characteristic. What will be the distribution of these two alleles in this plant's gametes?

Q 2.A phenotype ratio of 9:3:3:1 in the offspring of a mating of two organisms heterozygous for two traits is expected when: 3. Which of the following genetic crosses would be predicted to give a phenotypic ratio of 9:3:3:1?4. The gametes of a plant of genotype SsYy should have the genotypes:5. Which of the following genotypes would you not expect to find among the offspring of a SsYy x ssyy test cross:
