Question

Assertion : Hybrid is formed by a cross between two organisms that are different in one or more than one traits.

Reason : Mendel crossed two plants differing in one trait to obtain F1 plants which is monohybrid cross.

• 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 correct explanation of A
• C. A is true but R is false
• D. A and R are false

Answer 1

The correct option is B Both A and R are true but R is not correct explanation of A

The assertion that hybrid is formed by a cross between two organisms that are different in one or more than one traits is true. This is because recombination occurs forming a hybrid.

Mendel did obtain F1 plants by crossing two plants differing in one trait and this called a monohybrid cross. While this is true it is not the correct explanation of the assertion.
