Question

Assertion (A): Allopolyploidy involves numerical increase of the same genome.

Reason (R): Autopolyploidy develops through hybridisation between two species followed by doubling of chromosomes.

पर्याय

• Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

• Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

• Assertion (A) is true but reason (R) is false.

• Both assertion (A) and reason (R) are false.

Answer 1

Both assertion (A) and reason (R) are false.

Explanation:

Allopolyploidy involves chromosome sets from different species, not a numerical increase of the same genome. Autopolyploidy involves extra copies of the same genome; hybridisation between two species followed by chromosome doubling produces an allopolyploid.
