Question

Given below is the pedigree of sickle cell anaemia in a family.


In this, the RBC of both parents will be

• A. normal
• B. sickle shaped
• C. both normal and sickle shaped
• D. cannot be determined

Answer 1

The correct option is C both normal and sickle shaped

From the pedigree analysis, it has been found that the parents have offsprings which are affected by sickle cell anaemia. But both the parents are normal as seen in the pedigree. This is only possible when both the parents are carriers which means both the parents have normal and sickle shaped RBCs.
