Question

Choose the wrong statement with reference to Mutation theory.

• A. There are no intermediate stages in the course of evolution.
• B. Mutants arc markedly different from parents.
• C. Mutations are subjected to natural selection.
  
• D. Mutations are cumulated over generations.

Answer 1

Answer: (D)

Mutations are cumulated over generations.

Mutation theory was put forward by a Dutch scientist, Hugo de Vries. According to a theory, mutations are cumulated over generations, Hugo de Vries regarded mutations as the raw material for evolution. Mutants are markedly different form parents and there is no intermediate stages in course of evolution. Mutations are not subjected to natural selection, however later (natural selections) works on mutation, preserves the mutants having useful mutations and eradicates the mutants with harmful mutations.
