Multiple choice

Directions: Following question consists of two statements, one labeled as 'Assertion A' and the other labeled as 'Reason R'. You are to examine these two statements carefully and decide if the Assertion (A) and the Reason (R) are individually true and if so, whether the Reason is a correct explanation for Assertion. Select your answer from the codes given below.

A: If pollen of tall plant is transferred to the stigma of dwarf plant or pollen of dwarf plant is transferred to the stigma of tall plant, the F1 progeny were all tall

B: The sex of the plants have no influence over the inheritance of the characters R : The sex of the parents have no influence over the inheritance of the characters

  1. Both (A) and (R) are true and (R) is the correct explanation of (A)

  2. Both (A) and (R) are true and (R) is not the correct explanation of (A)

  3. (A) is true, but (R) is false

  4. (A) is false, but (R) is true

A Correct answer
Explanation

The assertion states that reciprocal crosses (tall male × dwarf female or dwarf male × tall female) produce identical F1 offspring (all tall). This demonstrates that inheritance is not influenced by the sex of the parent plant. The reason correctly explains this by stating that sex does not influence character inheritance - meaning the genetic contribution is equal regardless of which parent is male or female. This is true for Mendelian traits in plants like peas.
