Question

Assertion (A) : Apomictic embryos are genetically identical to the parent plant.

Reason (R) : Apomixis is the production of seeds without fertilisation.

• A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation for Assertion (A).
• B. Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation for Assertion (A).
• C. Assertion (A) is true, but Reason (R) is false.
• D. Assertion (A) is false, but Reason (R) is true.

Hint:

Apomixis gives seeds without fertilisation, so the embryo is a clone of the parent.

Answer 1

The Correct Option is A

Step 1: Check the Assertion:
In apomixis the embryo forms from a diploid cell of the ovule, such as a nucellus cell or the egg cell without fertilisation.
The cell has the same chromosomes as the parent. So the embryo is a clone. Assertion (A) is true.

Step 2: Check the Reason:
Apomixis is a form of asexual reproduction that mimics sexual reproduction. It makes seeds without fertilisation. So Reason (R) is true.

Step 3: Link them:
Since no meiosis or fusion of gametes takes place, no gene mixing happens. So the seeds without fertilisation give embryos identical to the parent.
R explains A. This is option (A).

Final Answer:
Both are true and R explains A, so the answer is option (A).
