'''Procreation''' is the process of conceiving and bearing offspring. It is the most essential activity of all forms of life, from the virus to man. In multicellular life (and even in some single-celled animals), procreation occurs as a result of sexual activity, in which genes are combined from a male and female of a species to produce offspring with hybrid vigor. | '''Procreation''' is the process of conceiving and bearing offspring.
