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.
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?
