Principle of Inheritance and Variation

184781 Statement (S) : The heterozy gous individuals for sickle- cell anemia \(\left(\mathbf{H b}^a \mathbf{H} b^3\right)\) express disease phenotype and also carriers of the disease.
Reason (R): \(\mathbf{H b}^{\mathbf{a}} \mathbf{H b}^3\) genotype individuals are resistant to severe effects of malaria.
The correct match is:

1 Both (S) and (R) are incorrect.
2 Both (S) and (R) are correct.
3 Both (S) and (R) are correct and (R) is suitable explanation to ( S ).
4 (S) is incorrect but (R) is correct.
