Which of the following does not show parthenogenesis?

The correct answer is Option (4) → Snakes

Option (1) Honeybees — Shows parthenogenesis. Male honeybees (drones) develop from unfertilised eggs.

Option (2) Turkey — Shows parthenogenesis. Turkey is named among the birds.

Option (3) Rotifers — Shows parthenogenesis.

Option (4) Snakes — Does not show it. NCERT names rotifers, honeybees, some lizards and birds (turkey) as organisms in which the female gamete develops into a new organism without fertilisation. Snakes are not in this list.

NCERT Extract (Pre-rationalised edition, Chapter 1, Reproduction in Organisms):
Fertilisation – “… However, it has to be mentioned here that in some organisms like rotifers, honeybees and even some lizards and birds (turkey), the female gamete undergoes development to form new organisms without fertilisation. This phenomenon is called parthenogenesis.”
