The allele for green shell (H) is dominant to the allele for a brown shell (h)
The phenotype ratio of generation two for group R is shown in the diagram
Which genotype could be placed in both boxes in generation one that would produce the phenotypes shown in generation two
One possible genotype for generation one that could produce the phenotypes shown in generation two is Hh. Since the allele for green shell is dominant, an individual with the genotype Hh would have a green shell. However, because the genotype also includes the recessive allele for brown shell, there is a possibility for their offspring to have a brown shell (if the offspring inherits the recessive allele from both parents). This would explain the phenotype ratio shown in generation two.
