Colorblindness is a sex linked trait in humans. Normal vision is a sex linked dominant trait. A man’s maternal grandmother had normal vision; his maternal grandfather was colorblind; his mother is colorblind; his father has normal vision.
1. What are the genotypes of the two grandparents and parents mentioned?

What type of vision does the man have himself?

What type have his sisters?

If he should marry a woman genotypically like one of his sisters (he is not marrying one of his sisters; calm down), what kind of vision would be expected in the offspring?

Bar eye (B) is a dominant and sex-linked trait of Drosophila. Curved wings (cu) and black body (bl) are recessive traits, both found on chromosome 2, separated by 24 map units. A homozygous Bar-eyed, black-bodied female is crossed to a true-breeding male expressing curved wings. The heterozygous F1 female is then crossed to a male expressing all three traits. At what frequency among the F2 would you expect to find a completely wild type male? How often would you find...

Hemophilia is a sex-linked trait. A hemophilic man, whose father was normal, marries a woman whose father had hemophilia and whose mother was heterozygous for hemophilia. What are the chances that their son will have hemophilia? A daughter will have hemophilia? (Since there are two possibilities for the mother, you must use the data from two Punnett Squares to answer these questions.) Mr. X has been accused by Miss Z of fathering her child. The child's blood type is AB...

Colorblindness is an X-linked recessive trait. Let us assume that a colorblind man has a colorblind sister and his mother has normal vision. What is the genotype, as to color vision, of this man’s mother and of his father? What kind of color vision will his sons and his daughters have, and in what ratios, if he marries a woman identical in genotype to his mother?

#9 In humans red-green colorblindness is inherited in an X-linked recessive pattern. Polydactyly (extra fingers and toes) is inherited in an autosomal dominant pattern. A woman with polydactyly (heterozygous) and normal vision marries a man with red-green colorblindness and normal fingers and toes. What phenotypes would you expect to see among their children?
