In peas the allele for inflated pods (I) is dominant to that for constricted pods (i), and the allele for green pods (G) is dominant to that for yellow pods (g). A plant of unknown genotype with inflated green pods is crossed with a plant with constricted yellow pods. Among the offspring all 93 plants have inflated green pods. What was the previously unknown genotype
