    1. A sex linked gene 'c' produces red-green color blindness in humans. A normal woman whose father is color-blind marries a color-blind man. What genotype(s) are/is possible for the mother of the color-blind man she has married?

    a. What are the chances that the first child from this marriage will be a color-blind boy?

    b. Of the daughters of these parents, what fraction are expected to be color-blind?
