AIIMS 2019 Zoology Somatic Hybridisation Assertion Reason Question
Assertion: Isolated protoplasts are used for somatic hybridisation Reason: Callus culture does not allow variation
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false
If both assertion and reason are false.
Correct Answer
Detailed Explanation
The assertion is true because isolated protoplasts are indeed used in somatic hybridization to facilitate the fusion of different plant cells, allowing for the creation of hybrid plants with desirable traits. However, the reason is false; callus culture can actually allow for variation through processes like somaclonal variation, which can lead to genetic diversity. Option A is incorrect because, while both statements are true, the reason does not correctly explain the assertion. Option C is incorrect since the assertion is true, and option D is incorrect as both statements are not false.
