Question

Study the pedigree chart of a family sharing the inheritance of sickle cell anemia.

The trait traced in the above pedigree chart is:

• A. Dominant X-linked
• B. Autosomal dominant
• C. Recessive X-linked
• D. Autosomal recessive

Hint:

Autosomal recessive traits often skip generations and affect both sexes equally.

Answer 1

The Correct Option is D

In the given pedigree, the trait appears in the offspring of unaffected parents, which is typical of a recessive trait. Moreover, both males and females are affected in roughly equal proportions, indicating autosomal inheritance rather than sex-linked. Therefore, this pattern corresponds to an autosomal recessive mode of inheritance.
