Reproduction may be asexual when one individual produces genetically identical offspring, or sexual when the genetic material from two individuals is combined to produce genetically diverse offspring. Asexual reproduction in animals occurs through fission, budding, fragmentation, and parthenogenesis.

fertilization-the process of fusion of sperm from male and ova from female is called fertilization.
internal fertilization-In this case fertilization takes place inside female body. for example:-humans, cows,dog etc.
external fertilization:- In this case fertilization takes place outside the female body. for example:- IVF(in vitro fertilization), aquatic animals etc.
zygote- during fertilization sperm from male and egg from female fuse to give rise a new cell called zygote.
embryo- the zygote divide itself and form different tissues and organs of the body. this stage of body is called embryo.
foetus- this is the stage of embryo in which all the body parts can be identified.
baby- when the foetus is completely developed, mother give birth to baby.
