Apomixis is the -

The correct answer is Option (3) → Form of asexual reproduction that mimics sexual reproduction

Apomixis is the formation of seeds without fertilisation, as in some grasses and Asteraceae. It is asexual, because no gametes fuse, yet it gives seeds, the usual product of sexual reproduction.

Option (1) Form of sexual reproduction that mimics sexual reproduction — Incorrect. Apomixis is not sexual: there is no fertilisation.

Option (2) Form of asexual reproduction that mimics asexual reproduction — Incorrect. What it imitates is sexual reproduction, by forming seeds.

Option (3) Form of asexual reproduction that mimics sexual reproduction — Correct. Apomixis is the production of seeds without fertilisation. No gametes fuse, so it is asexual; yet the plant still forms seeds, which is why it is said to imitate sexual reproduction.

Option (4) Form of asexual reproduction that does not mimics sexual reproduction — Incorrect. Since it forms seeds, it does imitate sexual reproduction.

NCERT Extract:
Apomixis and Polyembryony – “Although seeds, in general are the products of fertilisation, a few flowering plants such as some species of Asteraceae and grasses, have evolved a special mechanism, to produce seeds without fertilisation, called apomixis. Thus, apomixis is a form of asexual reproduction that mimics sexual reproduction.”
