Question

Discontinuous variations are :

• A. Essential features
• B. Acquired character
• C. Non-essential changes
• D. Mutations

Answer 1

The correct option is D Mutations

Discontinuous variations are where individuals fall into a number of distinct classes or categories and are based on features that cannot be measured across a complete range. You either have the characteristic or you don't.

Discontinuous variation is controlled by alleles of a single gene or a small number of genes. As variations caused by mutations affect DNA in such a way that either organism has a certain characteristic resulting from mutation or not, it is an example of discontinuous variations.

So, the correct answer is 'Mutations'
