Based on your knowledge of heredity, if the baby boy has Duchenne muscular dystrophy, then what else must be true?
- a. The baby’s father is a carrier of the Duchenne muscular dystrophy allele and passed along this trait to the baby.
- b. Duchenne muscular dystrophy is an autosomal-dominant disorder.
- c. Ashley is a carrier of the Duchenne muscular dystrophy allele but does not display symptoms because she has two X chromosomes, one of which is normal.
- d. If Ashley had a baby girl (instead of a baby boy), the baby girl would be at equal risk for having Duchenne muscular dystrophy.
