Answer:

Phenotypes are physical attributes. Genotypes are the alleles.

The phenotypes are 75% green peas and 25% yellow peas. This is because the capital G is a dominant allele and green is the dominant attribute and as long as 1 G is present, then the pea will appear green.

The genotypes are 25% GG, 50% Gg, and 25% gg.
