Question

Assertion: Mitosis maintains the genetic similarity of somatic cells.
Reason: Chromosomes do not undergo crossing over.

• A. Both assertion and reason are true and the reason is the correct explanation for the assertion.
• B. Both the reason and assertion are true but the reason is not the correct explanation for the assertion
• C. Assertion is true but reason is false
• D. Both the reason and assertion are false

Answer 1

The correct option is A Both assertion and reason are true and the reason is the correct explanation for the assertion.

Mitosis keeps all the somatic cells of an organism genetically similar, resembling the fertilized egg.
Mitosis involves replication and equitable distribution of all the chromosomes so that all the cells of multicellular organism have the same number and type of chromosomes. This helps in proper coordination among different cells.
