Assertion : Mendel conducted artificial ...

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

Text Solution

Verified by Experts

The correct Answer is:
A
Mendel carried out 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 produce offspring resembling the parents. These lines show the stable trait inheritance and expression for several generations making them suitable for genetic studies.
