Mendel performed a cross between individuals heterozygous for three different traits: yellow versus green seeds (green is dominant), red versus white flowers (red is dominant), and green versus yellow pods (green is dominant). What fraction of the offspring would have been expected to have green seeds, red flowers, and green pods?

Mendel's law of independent assortment states that the alleles of different genes assort independently of one another during gamete formation. This means that the probability of inheriting a particular allele for one gene is not affected by the probability of inheriting a particular allele for another gene. In this case, the probability of inheriting a green seed allele is 1/2, the probability of inheriting a red flower allele is 1/2, and the probability of inheriting a green pod allele is 1/2. Therefore, the probability of inheriting all three dominant alleles is (1/2) * (1/2) * (1/2) = 1/8.
