Question

Quizplus · Accepted Answer

Duchenne muscular dystrophy is caused by a mutation in the dystrophin gene, which is located on the X chromosome. Since males only inherit one X chromosome (from their mother), they are more likely to express the disease if they inherit the mutated gene. Females are carriers of the gene and can pass it down to their offspring. This pattern of inheritance is known as X-linked recessive. Tay-Sachs disease is autosomal recessive, and cystic fibrosis is autosomal recessive or, in rare cases, inherited in an X-linked recessive pattern.
