Answer:

GG, Gg, Gg, gg

Homozygous green – GG

Heterozygous green – Gg

Homozygous yellow - gg

Explanation:

It is given that allele for green seed pods (G) is dominant to the allele for yellow seed pods (g) which means that if “G” and “g” occur together, a trait associated with G will be expressed.  

The genotype of the true breeding Green plant is “GG”  

The genotype of the true-breeding yellow plant is “gg”  

F1 generation cross  

GG * gg

Offspring produced from F1 generation are – Gg, Gg, Gg, Gg

In f2 generation offspring of F1 generation are crossed among each other.  

So the offspring produced in F2 generation are  

Gg * Gg

GG, Gg, Gg, gg

Homozygous green – GG

Heterozygous green – Gg

Homozygous yellow - gg
