Mutations. They are unpredictable, stable and inheritable changes which occur in the organisms due to permanent changes in chromosome number, chromosome structure and genes. Mutations were called sports by Darwin (1859), and discontinuous variations by Bateson (1894). The term mutation was coined by Hugo de Vries (1901).
