In a family, where both parents have normal vision, there was born a son with daltonism and two daugh-ters with normal vision. The first son has a son with normal vision. The children of the first daughter are a son with daltonism and a daughter with normal sight. The second daughter has five healthy sons. Draw the pedigree of the family. Determine the probability of birth of the healthy sons in a family of first daughter.

The probability of healthy sons to the first daughter would be 3/4, since daltonism is a recessive X-linked trait and that it affects male than it does to females.
