In humans, genetic variations are caused because humans reproduce by a sexual life cycle which is termed as meiosis. In such a life cycle, the offspring receives half the chromosomes from the mother and half from the father.

During crossing over, the exchange of DNA segments between the homologous chromosomes takes place which brings about the genetic variations.
