Answer:
When a woman who has normal vision (NN) has a child with a man who has glaucoma (GG), which is a dominant condition, all their children (100%) will inherit one normal allele (N) from the mother and one glaucoma allele (G) from the father. Even though they have one normal allele, the presence of the dominant glaucoma allele will cause them to have glaucoma and exhibit the glaucoma phenotype. So, all their children will have glaucoma.

Answer:
To show the cross between a woman who is homozygous normal for vision (NN) and a man who is homozygous for glaucoma (GG), where glaucoma is dominant to normal vision (N):
Genotype of the woman: NN
Genotype of the man: GG
Since glaucoma is dominant to normal vision, the genotype for glaucoma will be expressed if present. Therefore, the genotype of the man will determine the outcome of the offspring.
Possible genotypes of the offspring:
- All offspring will be heterozygous for glaucoma (NG) since the man is homozygous for glaucoma (GG) and can only pass on the G allele.
Phenotypes of the offspring:
- All offspring will have glaucoma, as the G allele for glaucoma is dominant to the N allele for normal vision.
