refer to the figure showing a pedigree of a family affected by a sex-linked recessive disorder. if a female is a carrier for a sex-linked recessive disorder, is it possible for her sons to be unaffected by the disorder? choose the best answer and explanation.
a. yes, this is possible. males receive an x chromosome from their mother. if their mother is a carrier, a male has a 50 percent chance of being affected by the disease and a 50 percent chance of being unaffected.
b. no, this isn't possible. if a mother is a carrier of an x-linked recessive disorder, her sons will be affected by the disease and her daughters will be carriers of the disease.
c. no, this isn't possible. x-linked recessive disorders can't "skip" generations like other genetic disorders.
d. yes, this is possible. males receive an x chromosome from their mother. if their mother is a carrier, the mutated x chromosome won't be passed on to sons and so they'll be unaffected.
