A dihybrid cross involves a study of inheritance patterns for organisms differing in two traits. Consider Mendel's experiments with pea plants. If we look at two traits of Mendel's peas, say seed shape and seed color, we will see that these two traits are inherited independently. 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. Since this is a dihybrid cross, the genotype for each parent is SsYy. Can you determine which statements are correct regarding a dihybrid cross between SsYy X SsYy?
