what are the two types of fertilization occurring in animal sexual reproduction ?
FERTILIZATION
Fertilization is the process by which male and female gametes are fused together, initiating the development of a new organism.

INTERNALFERTILIZATION
In sexual reproduction, the male inserts the sperms into the female reproductive tract to fuse with the egg. If the fusion takes place within the female parent, it is called internal fertilization. In humans, most of the animals like cats, lions, pigs, dogs, hens, etc., the fusion of gametes takes place internally. In this type, a zygote is formed within the mother and gets its nourishment from her.
EXTERNALFERTILIZATION
When the fusion of sperm and egg takes place outside the female parent, it is called external fertilization. Only a minority of organisms exhibit this type of gamete fusion. For example, fish, frogs, etc. Here the female parent deposits her eggs in a place and later, the male parent ejects his sperms over them, then fusion takes place.
Animals which use viviparous and ovoviviparous reproduction (embryos develop within the animal's body), and oviparous animals which lay hard shelled eggs, use internal fertilization. Internal fertilization involves the union of sperm and eggs within the body of the (usually female) parent.
