Determine the correctness or otherwise of the following Assertion (a) and the Reason (r)
Assertion: Cytoplasmic male sterility (cms) is invariably due to defect(s) in mitochondrial function.
Reason: cms can be overcome by pollinating a fertility restoring (Rf) plant with pollen from a non cms plant.
(A) both (a) and (r) are true and (r) is the correct reason for (a)
(B) both (a) and (r) are true and (r) is not the correct reason for (a)
(C) (a) is false but (r) is true
(D) (a) is true but (r) is false
Answer
Answer: (A) both (a) and (r) are true and (r) is the correct reason for (a)
Cytoplasmic male sterility (cms) is indeed typically due to mitochondrial defects, and the condition can be overcome by using a fertility restoring (Rf) plant, which is the correct reason for the assertion.
