Answer:

The genotype of a plant with bumpy pods would be aa, while the genotype of a plant with smooth pods would have to be either AA or Aa.

Explanation:

The smooth pod allele ("A") is dominant, which means it overwrites the bumpy pod allele ("a"), which is recessive.

Because of this, all genotypes with at least one "A" in them are smooth. This includes "AA" and "Aa."

The only way for a pod to be bumpy here is if there aren't any dominant alleles to nullify it. That means plants with bumpy pods can only have the "aa" genotype.

[Note: I didn't use the letter "a" for any particular reason. The specific letter isn't relevant here.]
