E) all peas with inflated pods.

In this cross, one parent is heterozygous (Ii) for the trait, meaning they have one dominant allele (I) for inflated pods and one recessive allele (i) for constricted pods. The other parent is homozygous recessive (ii), meaning they have two recessive alleles for constricted pods. The offspring will have a 1:1 ratio of Ii (inflated pods) to ii (constricted pods), resulting in half with inflated and half with constricted pods.
