Nearsightedness is dominant to normal vision and hazel eyes are dominant to blue eyes. A nearsighted woman with hazel eyes who is heterozygous for both traits marries a man with normal vision and hazel eyes. His genotype for eye color is the same as his wife's. Their three children all have blue eyes and normal vision. What is the probability that their next child will have blue eyes and be nearsighted? 1/4 1/2 3/8 1/8 5/8

Step 1
The nearsighted woman with hazel eyes is heterozygous for both traits, so her genotype is $NnHh$. The man has normal vision and hazel eyes, and his eye color genotype is the same as his wife's. This means his genotype is $nnHh$. Show more…

Nearsightedness is dominant to normal vision, and hazel eyes are dominant to blue eyes. A nearsighted woman with hazel eyes, who is heterozygous for both traits, marries a man with normal vision and hazel eyes. His genotype for eye color is the same as his wife's. Their three children all have blue eyes and normal vision. What is the probability that their next child will have blue eyes and be nearsighted?

A nearsighted woman (Nn) with hazel eyes (Hh) marries a man with normal vision and hazel eyes (Hh). Their three children all have blue eyes and normal vision. What is the probability that their next child will have blue eyes and be nearsighted? A. 1/4 B. 1/2 C. 3/8 D. 1/8 E. 5/8 Draw a punnet square to explain
At an autosomal gene locus in humans, the allele for brown eyes is dominant over the allele for blue eyes. At another gene locus, located on the X chromosome, a recessive allele produces colorblindness while the dominant allele produces normal color vision. A heterozygous brown-eyed woman who is a carrier of colorblindness has children with a blue-eyed man who is not colorblind. What is the probability that their first child will be a blue-eyed female who has normal color vision? (Enter the probability as a percent. Enter the number only without the percent sign. For example, enter 100% as 100 and enter 12.5% as 12.5)
