Answer:
a) Genotype ratio= 1/2 Gg: 1/2 gg
Phenotype ratio = 1/2 yellow seeds: 1/2 green seeds
b) Genotype ratio= 1/4 GG : 1/2 Gg: 1/4 gg
Phenotype ratio= 3/4 yellow seeds : 1/4 green seeds
Explanation:
a) Genotype of heterozygote parent plant = Gg
Genotype of homozygous recessive parent plant= gg
A cross between Gg x gg gives progeny in following ratio= 1/2 Gg (yellow seeds) : 1/2 gg (green seeds)
b) Parent plants = GG x gg
F1= Gg
A cross between Gg x Gg would give F2 progeny in following ratio= 1/4 GG (yellow seeds): 1/2 Gg (yellow seeds) : 1/4 (green seeds)
