The offspring that can be described by the genotype is
Gg while for the phenotype is
green pod color
The cross between GG and gg give a heterozygous offspring that Gg offspring. The offspring are have a green pod color since the green pod color is dominant over yellow pod color and therefore the offspring have a green pod color. The cross is as the punnet square below.
