I have been asked this question during an interview.

My question is based upon Mechanism of Evolution in section Evolution of Biology – Class 12

Answer 1

The correct choice is (b) Saltation

For explanation: Single-step that causes large mutation is called saltation. It is called as such because the mutation occurs suddenly and abruptly that leads to evolution in large scale. Hugo de Vries used this term against Darwin’s theory of evolution.
