| 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] True breeding lines have stable trait inheritance for several generations. |
| Reason [R] Mendel conducted cross-pollination experiments on true breeding lines. |
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: B
Solution :
[b] Both A and R are true, but R is not the correct explanation of A. True breeding lines show inheritance of pure characters for several generations. This is because true breeding lines are homozygous for the traits. Therefore, Mendel conducted cross-pollination experiments, between different true breeding lines to study the concept of inheritance.
