Pedigree — Definition & Charts

By Sylvia Freeman
This image is showing a pedigree chart. The mother is affected and the father is unaffected. They have three children: A carrier daughter, an affected son, and a third daughter with an unknown phenotype. The unknown daughter has one son, who is affected. All of the other children's children and all of the children's spouses are unaffected and are not carriers.

If the blue trait shows an X-linked recessive pattern of inheritance, what is the genotype of the woman on the far right?
