According to Hugo de Vries, mutations play an important role in speciation although they are random and directionless. These mutations were termed (a) Saltations (b) Founder effect (c) Bottle neck effect (d) Variations

Assertion :- According to Hugo de Vries , it is mutation which causes speciation and hence called it saltation. Reason :- Mutations are random and diretional.
