Variation in the individuals either induced by environment or due to the hereditary change during genetic recombinations. But the variations or changes which suddenly appear in an individual and can be inherited to the progeny, is called mutation (Dwain).
According tobateson: Mutation is discontinuous variation.
According to sinnot DON, Dobznhansky, Mutation is any change in gene or genotype.
According to hugodevries mutation is defined as any sudden and drastic heritable change in gene which is not traceable or ascribable to segregation or recombination. He first recognised the sudden changes in Oenothera Lamarkiana and studied the hereditary and came to this condition in 1901.
Mutations may be induced or natural it is brought about by any change in the genetic makeup either in chromosome level or in gene level. It may be structural or compositional or numerical changes which cause the change in character of an individual. A character may be lost or gained.
Mutation play important role in plant breeding and also displays the key role in evolution of species.
