The essential requisites for sexual reproduction includes:
  1. There should be distinguished male and female parts if present in the same body or distinguished male and female bodies producing separate germ cells to carry out the reproduction process.
  2. If the male and female are two different bodies then they must belong to the same species, for production of a viable generation. Mating between two different species may or may not lead to a viable progeny generation.
