Detailed explanation-2: -A hybrid organism is one that is heterozygous, which means that is carries two different alleles at a particular genetic position, or locus.

Detailed explanation-3: -Since the plant with the green pods is heterozygous for the trait, its genotype must be Gg.

Detailed explanation-4: -No, AA/bb is a pure-bred genotype, but Aa/Bb is a hybrid genotype. The possible genotypes of the pure-bred plants are AA/bb and aa/BB. Shull found that when he crossed the two pure-breds, the offspring grew much better.
