GENERAL KNOWLEDGE

Detailed explanation-1: -In oviparity, fertilized eggs are laid outside the female’s body and develop there, receiving nourishment from the yolk that is a part of the egg. This occurs in most bony fish, many reptiles, some cartilaginous fish, most amphibians, two mammals, and all birds.

Detailed explanation-2: -Internal fertilization is characterized by sperm fertilizing the egg within the female; the three methods include: oviparity (egg laid outside female body), ovoviparity (egg held within female), and viviparity (development within female followed by live birth).

Detailed explanation-3: -Oviparous animals lay eggs. Examples include chickens, ducks, and snakes. Ovoviviparous animals have eggs that develop inside the mother’s body, but the eggs are not fertilized by the father. The babies are born live. Examples include sharks and some fish.
