MCQ
Assertion: Mendel used true-breeding pea lines for artificial pollination experiments for his genetic studies.
Reason: For several generations, a true-breeding line shows the stable trait inheritance and expression.
  • ✓
    Both A and R are True.
  • B
    Both A and R are False.
  • C
    A is True and R is False.
  • D
    A is False and R is True.
✓

Answer

Correct option: A.
Both A and R are True.
(a) Both A and R are True.
Explanation:
Mendel carried out the hybridisation experiments on garden pea for many years. He performed various types of cross breeding and then allowed the offspring to self-breed. All selected varieties used by him were pure lines of true breeding lines, i.e., they produced offspring resembling the parents. These true breeding lines show the stable trait inheritance and expression for several generations making them suitable for genetic studies.
