Answer:
Genotype of the male parent: Homozygous (RR)
Phenotype of the male parent: Round seeds
Gametes for the male parent: R and R
Genotype of the female parent: Heterozygous Rr
Phenotype of the female parent: Round seeds
Gametes for the female parent: R and r
To determine the genotypic and phenotypic ratio of the offspring, lets make a punnet square:
R r
R RR Rr
R RR Rr
Genotype ratio of the offspring: 2:2
50% of the offspring will be homozygous round whereas 50% will be heterozygous round.
Phenotypic ratio of the offspring: 1
All of the offspring will be round hence the phenotypic ration will be 1 (100%).
