Question

Genetic variation occurs during

• A. Cell-cell interaction
• B. Gene interaction
• C. Cell differentiation
• D. None of the above

Answer 1

The correct option is C Cell differentiation

Differentiation is the process where the cell takes up a specialised function and go on to form tissues and organs. This information is stored in the genetic material of the organism and is passed on from the parents to the offspring. The differentiation is controlled by the gene expression.

During this, there is a slight change in the constitution of the genetic material of the offspring from the parents and that lead to the variations that arise in the population.

So, the correct option is 'Cell differentiation'.
