The genotypes and phenotypes of the offspring is determined by the parents.
What will be the genotype and phenotype of the offspring of the cross?
Assuming G is dominant over g, the offspring of the cross between the parents whose genotypes are Gg and Gg are given below:
- Gg x Gg = GG, Gg, gg, and Gg
Probability of a gray offspring = 0.75
Probability of an albino offspring = 0.25
There are three possible genotypes; GG, gg, and Gg
There are two possible phenotypes; gray and albino
Probability of getting heterozygous offspring, Gg = 0.5
Probability of getting h0m0zygous offspring, GG and gg = 0.5
The color of the female is gray
The color of the male is gray
Assuming G is dominant over g, the offspring of the cross between the parents whose genotypes are gg and Gg are given below:
- gg x Gg = Gg, Gg, gg, and gg
Probability of a gray offspring = 0.5
Probability of an albino offspring = 0.5

Probability of getting h0m0zygous offspring, gg = 0.5
The color of the female is albino
The color of the male is gray
Therefore, the genotypes and phenotypes of the offspring is determined by the parents.
