Below is a pedigree of a family with a history of X-linked recessive color blindness. We will use XB to represent the wild-type allele and xb to represent the mutant allele of the gene that leads to color blindness. The color vision status of the individuals with a question mark (?) is unknown.

Below is a pedigree of a family with a history of X-linked recessive color blindness. We will use XB to represent the wild-type allele and Xxb to represent the mutant allele of the gene that leads to color blindness.
