Question

Duchenne muscular dystrophy is an example of:

• A. X-linked dominant inheritance
• B. X-linked recessive inheritance
• C. Autosomal recessive inheritance
• D. Y-linked dominant inheritance

Hint:

In X-linked recessive inheritance, males are more likely to be affected because they have only one X chromosome, while females have two and typically need two copies of the defective gene to show symptoms.

Answer 1

The Correct Option is B

Duchenne muscular dystrophy (DMD) is an X-linked recessive disorder, meaning the gene responsible for DMD is located on the X chromosome. Males are more commonly affected since they have only one X chromosome.
