Refer to the figure showing a pedigree of a family affected by an x-linked recessive disorder. a female in generation 3 isn't a carrier of the disorder. how can this be?
a. females receive x chromosomes from this fathers only, which are unaffected in this case.
b. females don't have x chromosomes so aren't affected by gene disorders passed on the x chromosome.
c. females receive an x chromosomes from each point parent, but in cases of recessive disorders, the muted chromosome isn't passed on to daughters.
d. females receive an x chromosome from each parent. if a mother is a carrier of an x-linked recessive disorder, her daughters have 50 percent chance of receiving her normal x chromosome and a 50 percent chance of receiving her mutated x chromosome.
