Reproduction is the process of producing individuals of the same kind. Most of the organisms reproduce by mating which increases the genetic variability of the organism. The males and females have separate reproductive organs known as gonads. These gonads produce gametes that fuse together to form a single cell called the zygote.
Depending on the number of parents involved, there are different modes of reproduction. In animals is two types of reproduction: Sexual Reproduction and Asexual Reproduction.
Sexual Reproduction-
The process in which the male and female gametes fuse together to form a new individual is called sexual reproduction. Examples-Humans, dogs, cats, horses, etc.
Asexual Reproduction-
Besides sexual reproduction, the other major type of reproduction seen in the animal kingdom is asexual reproduction. This type of reproduction is mostly observed in lower organisms and unicellular microbes. It is the process in which a new individual is formed by the involvement of a single parent without the involvement of the gamete formation.
Examples-Insects, hens, fish, amphibians.
