Question

Which of the following diseases has autosomal recessive inheritance?

• A. Osteogenesis imperfecta
• B. Treacher Collins syndrome
• C. Achondroplasia
• D. Cystic fibrosis

Hint:

Autosomal recessive diseases require both parents to be carriers for the child to inherit the condition.

Answer 1

The Correct Option is D

The disease with autosomal recessive inheritance is Cystic fibrosis. Cystic fibrosis is a genetic disorder caused by mutations in the CFTR gene, and it follows an autosomal recessive inheritance pattern. Both parents must carry a copy of the mutated gene for the disease to manifest in the child. Osteogenesis imperfecta and Achondroplasia are examples of autosomal dominant conditions, while Treacher Collins syndrome can have both dominant and recessive inheritance patterns depending on the mutation.
