| Direction: Each of these questions contains two statements |
| Assertion [A] and Reason [R]. Each of these questions also has four alternative choices, any one of which is the correct answer. You have to select one of the codes [a], [b], [c] and [d] given below. |
| Assertion [A] Haemophilia is a genetically linked disease. |
| Reason [R] It is predominantly found in females. |
A) Both A and R are true and R is the correct explanation of A
B) Both A and R are true, but R is not the correct explanation of A
C) A is true, but R is false
D) A is false, but R is true
Correct Answer: C
Solution :
[c] A is true, but R is false. R can be corrected as Haemophilia predominantly occurs in males, since the gene can be passed from mother to son. A single copy of defected gene can cause disease in males. In contrast, woman is affected in the presence of two defected alleles which is a rare phenomena.
