Question

Which of the following is a dominant autosomal disorder?

• A. Cystic Fibrosis
• B. Huntington's Disease
• C. Sickle Cell Anemia
• D. Hemophilia

Hint:

Dominant autosomal disorders require only one copy of the altered gene to be inherited for the disorder to be expressed in an individual.

Answer 1

The Correct Option is B

Huntington's Disease is a dominant autosomal disorder, meaning only one copy of the mutated gene is sufficient to cause the disease. In contrast, disorders like Cystic Fibrosis and Sickle Cell Anemia are recessive, requiring two copies of the mutated gene. Hemophilia is typically an X-linked recessive disorder.
