A dihybrid cross involves a study of inheritance patterns for organisms differing in two traits. Mendel studied dihybrid crosses and determined that different traits of pea plants, such as flower color and seed shape, were Inherited independently. In pea plants, 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.
A pea plant is heterozygous for both seed shape and seed color. What will be the distribution of these two alleles in this plant's gametes?
