Question

Which of the following is an example of an autosomal recessive genetic disorder?
A) hemophilia A
B) Duchenne muscular dystrophy
C) Marfan syndrome
D) brachydactyly
E) cystic fibrosis (CF)

Accepted Answer

Cystic fibrosis is an example of an autosomal recessive genetic disorder. It is caused by mutations in the CFTR gene, and individuals must inherit two copies of the mutated gene (one from each parent) to develop the disease. Hemophilia A is an X-linked recessive disorder, Duchenne muscular dystrophy is an X-linked recessive disorder, Marfan syndrome is an autosomal dominant disorder, and brachydactyly can be caused by multiple genetic factors.
