Sexual reproduction is a phenomenon in which new organisms are formed as a result of a combination of the genetic material of the individuals that have different sexes. This genetic information is present in the chromosomes of the sex cells. The sex cells are also termed as gametes. The male and female gametes are known as sperms and ova respectively.
During sexual reproduction, the sperm and the ovum undergo the process of fertilization and form a zygote. This zygote has half its DNA from the mother and half from the father. In this way, the offspring is similar to both mother and father but is not identical to any of them. This type of reproduction is present in multi-cellular organisms like animals and plants.
