Question

Assertion : Mendel conducted artificial pollination experiments for his genetic studies using true-breeding pea lines.
Reason : A true-breeding line shows the stable trait inheritance and expression for several generations.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (A)

Mendel carried out hybridisation experiments on garden pea for many years. Fie 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 produce offspring resembling the parents. These lines show the stable trait inheritance and expression for several generations making them suitable for genetic studies.
