Open in App
Solution
The correct option is C will be both normal and sickle shaped
From the pedigree analysis, it has been found that the parents of I generation have offspring which are affected by sickle cell anaemia. But both the parents show normal phenotype 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.
