Based on the Punnett square diagrams given here,
(A) the genotype of the offspring of F1 generation will be Gg.
(B) the phenotype of the offspring in the F1 generation will be having grey seed coat.
About genotype and phenotype
Genotype is basically the set of genes responsible for a specific genetic trait.
Here for the genotype for the color of the seed coat which is Gg for the F1 generation.
Phenotype characteristics describes the physical appearances based on the genotype of plant.
Since G is dominant allele in the plant for grey seed coat, the offspring of F1 generation having Gg genotype will have phenotype character of grey seed coat.
