Mutation :

 Sudden heritable change in genetic material of an organism is called as Mutation.

 Mutation are discontinuous source of variation.

 Frequency of mutation at present is 1 × 10–6 (1 cell in : 1 million-cell). But it will increase in future due to pollution and destruction of ozone layer.

 Mutation word was given by Hugo De Vries.

De Vries studied mutations in the plant Oenothera lamarckiana(evening primrose). It is a hybrid plant.

 De Vries gave (proposed) mutation theory of evolution.

 This theory was given in support of Darwinism because Darwin was unable to explain the source of variations.

Darwin called variation assport.
