Ovipary:

(i) Oviparous animals lay fertilized or unfertilized eggs.

(ii) The fertilized eggs remain covered by hard calcareous shell and laid in safe place in the environment. After a period of incubation young ones hatch out.

(iii) Chances of survival of young ones is less as the female lay egg in the open environment.

Examples: Birds and reptiles

Vivipary:

(i) Viviparous animals give birth to young ones.

(ii) The fertilized egg (zygote) develop into a young one inside the body of the female organism.

(iii) Chances of survival of young one is more because of proper embryonic care and protection inside the mother's body.

Examples: Most of the mammals like human, cow, lion, tiger, horse, rat, cat, dog, etc.
