Duchenne muscular dystrophy is a serious condition caused by a recessive allele of a gene on the human X chromosome. The patient
klio [65]

Answer:

One-half of the daughters of an affected man would have this condition.

Explanation:

Each daughter born to a woman that is positive for a dystrophin mutation on one of her two X chromosomes possess a 50 percent likelihood of possessing the mutation and also becoming a carrier. Carriers at times do not show the disease symptoms but may give birth to a child that has the mutation or the disease condition. DMD carriers do have a higher chance of cardiomyopathy.

A man with DMD cannot transfer the affected gene to his sons since he passes to his son a Y chromosome, not the X chromosome. But he will definately transfer it to his daughters, since each daughter possess her father’s only X chromosome resulting in the daughters being carriers.

Hence, One-half of the daughters of an affected father and a carrier mother could have this condition.
