Life has evolved from simple stages to more complex ones, and so have the reproduction mechanisms.
Initially the reproduction was a replicating process that consists in producing new individuals that contain the same genetic information as the original or parent individual.
This mode of reproduction is called asexual, and it is still used by many species, particularly unicellular, but it is also very common in multicellular organisms, including many of those with sexual reproduction.
In sexual reproduction, the genetic material of the offspring comes from two different individuals.
Typically, prior to an asexual division, a cell duplicates its genetic information content, and then divides. In sexual reproduction, there are special kinds of cells that divide without prior duplication of its genetic material, in a process named meiosis.In addition to animals, plants, and fungi, other eukaryotes (e.g.
