Question

Which of the following statement does not favour the mutation theory?

• A. It is saltatory process
• B. They are ultimate source of variation
• C. Mutation fluctuate around the normal traits and is directional
• D. Create genetic variation

Answer 1

The correct option is C Mutation fluctuate around the normal traits and is directional

Mutation refers to the alteration in the sequence of the original gene due to various factors such as mismatching of the nucleotide sequence. The mutation theory does not favour that mutation fluctuates around normal traits and is directional. Mutation refers to a saltatory process, and it leads to create variations among species. Mutation theory suggests that mutation is inheritable and it creates genetic variation. It is not bounded to a single direction, mutations can happen in all possible directions.

So, the correct answer is 'Mutation fluctuate around the normal traits and is directional'.
