Duchenne muscular dystrophy is a genetic disorder that arises from a recessive X-linked allele. Why is this disorder almost always restricted to males?

AMales have XX chromosomes and therefore have a higher chance of carrying both recessive alleles for this genetic disorder.
BFemales have XX chromosomes and therefore have a very low chance of carrying both recessive alleles for this genetic disorder.
CFemales have XX chromosomes and therefore have a higher chance of carrying both recessive alleles for this genetic disorder.

Duchenne muscular dystrophy is a genetic disorder that arises from a recessive X-linked allele and is almost restricted to males because females have XX chromosomes and therefore have a very low chance of carrying both recessive alleles for this genetic disorder. The correct answer would be option B.
