Question

Animals in which development of zygote takes place inside the body of a female parent, i.e., they give birth to young ones are called

• A. Viviparous
• B. Marsupials
  
• C. Oviparous
  
• D. Ovoviviparous
  

Answer 1

The correct option is A Viviparous

Oviparous
In oviparous animals, the females lay either fertilised or unfertilised eggs which are fertilised externally. Thus, the development of the zygote happens outside the body of the mother.

Viviparous
Viviparous animals are those in which the zygote develops within the mother’s body and the females directly give birth to young ones.

Ovoviviparous
Ovoviviparous animals produce eggs which hatch inside the body of the mother. In this case the fertilisation and zygote development is within the body.

Marsupials
Marsupials give premature birth to offspring which continue to develop while being attached to the mother’s body.

Final answer
(b) Viviparous
