Question

Example of asexual reproduction with gamete formation

Answer 1

Asexual reproduction may involve gametic formation but there is no gametic fusion. This

line of NCERT is absolutely correct. One good example for this is parthenogenesis. It

involves development of complete individual from gamete without fertilisation.

Example 1: Fungi and Algae (some)

Gamete (n) --(No Syngamy, Modified into spore)--->Parthenospore/Azygospore ----->New individual

Thick walled spores (Parthenospore, azygospore) are produced by parthenogenesis in

certain alga and fungi from gamete without gametic fusion. Under favourable conditions

spores germinate to form new individual. So here gamete formation is present but

gametic fusion is absent.

Example 2: Honey bees

Egg (n) ----> without fertilisation

Male bee (n) (Drone
