2. In humans, brown eyes are usually dominant over blue eyes. Suppose a blue-eyed man marries a brown-eyed woman whose father was blue eyed. What proportion of their children would you predict would have blue eyes? 3. A brown-eyed man whose father was brown eyed and whose mother was blue eyed married a blue eyed woman whose father and mother were both brown-eyed. The couple has a blue-eyed son. For which of the individuals mentioned can you be sure of the genotypes? What are their genotypes? What genotypes are possible for the others?
