Assertion: Genetic variations provide raw material for selection.
Reason: Genetic variations are differences in genotypes of the individuals.

A

Both Assertion and Reason are true and Reason is correct explanation of Assertion.

B

Both Assertion and Reason are true, but reason is not the correct explanation of Assertion

C

Assertion is true, but the Reason is false

D

Assertion is false, but the Reason is true

Text Solution

Verified by Experts

The correct Answer is:
B
Creation of genetic variation and selection are the two critical steps in the plant breeding. Genetic variations are difference in genotypes of the individuals which airse due to genetic reasons. Genetic variations provides the raw material for selection and selection effects the desired improvement.
