Problem

A husband and wife have normal vision, although both of their fathers are red-green color-blind, an inherited X-linked recessive condition.

A. Give the genotypes of the husband and wife.

B. What is the probability that their first child will be:

B.1. a normal son?

B.2. A normal daughter?

B.3. A color-blind son?

B.4. A color-blind daughter?

Solution

A. The X-chromosomes from fathers will not be passed along to the son. This sole X-chromosome will always be passed to their daughters. Thus, the husband will have a normal XY genotype and the wife will have an XcX genotype.
