PUNNETT SQUARE Pea plants protect their seeds in pouch-like cases called pods. Some pea plants grow inflated pods, which are smooth. Other pea plants grow constricted pods, which are bumpy. In a group of pea plants, some individuals have inflated pods and others have constricted pods. In this group, the gene for the pod shape trait has two alleles. The allele for inflated pods (D) is dominant over the allele for constricted pods (d). Complete the Punnett square below to show all possible genotypes of the offspring from a cross between two pea plants.​
