Question

Assertion: When pure breed tall plants are crossed with pure breed short plants, all the plants in F₁ progeny are tall. When the tall plants of F₁ progeny are crossed, short plants re-appear in F₂ progeny.

Reason: Traits are independently inherited.

विकल्प

• Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion.

• The Assertion and the Reason are correct but the Reason is not the correct explanation of the Assertion.

• The assertion is true but the Reason is false.

• The statement of the Assertion is false but the Reason is true.

Answer 1

The Assertion and the Reason are correct but the Reason is not the correct explanation of the Assertion.

Explanation:

• Assertion is true because in a monohybrid cross (Tall × Short), all F₁ plants are tall, and short plants reappear in F₂ due to segregation of alleles.
• Reason is true in general, but it talks about independent assortment, which applies to two traits, not one.

So both are correct, but the Reason does NOT explain the Assertion.
