Question

Which of the following is incorrect with respect to mutation?

(a) Sudden

(b) Continuous

(c) Change in chromosomes and genes

(d) Leads to variation in DNA

I had been asked this question in a job interview.

My question is taken from Inheritance and Variation Principles in chapter Principles of Inheritance and Variation of Biology – Class 12

Answer 1

The correct option is (b) Continuous

Explanation: Mutations are not continuous. Instead, mutations are discontinuous variations in the genotype and phenotype of an organism. This is due to the changes in chromosomes and DNA. Mutations are sudden and they are a cause of the variation in DNA.
