Question

Given below are two statements, one is labelled as Assertion (A) and other labelled as Reason (R).
• [Assertion (A):] In nature, the tetraploid and hexaploid wheat reproduce as diploid (\(2n=28\) or \(2n = 42\)). 
• [Reason (R):] In the presence of the Ph1 allele in chromosome 5B, each chromosome pairs only with its homologue from the same genome and reproduces as diploid. 
In light of the above statements, choose the correct answer from the options given below. 
 

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
• C. (A) is true but (R) is false.
• D. (A) is false but (R) is true.

Hint:

The Ph1 gene on chromosome 5B is a vital genetic switch in wheat cytogenetics.
Its function allows allopolyploid wheat to maintain stable, diploid-like inheritance over generations.

Answer 1

The Correct Option is A
