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

Males have XX chromosomes and therefore have a higher chance of carrying both recessive alleles for this genetic disorder.

Females have XX chromosomes and therefore have a very low chance of carrying both recessive alleles for this genetic disorder.

Females have XX chromosomes and therefore have a higher chance of carrying both recessive alleles for this genetic disorder.
