Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: Gametophytic self incompatibility was first described by Hughes and Babcock in Crepis foetida.
Reason R: In gametophytic system, incompatibility reaction of pollen is determined by its own genotype and not by the genotype of the plant on which it is produced.
In light of the above statements, choose the most appropriate answer from the options given below:

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is NOT the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Hint:

Gametophytic SI = Pollen's own genotype.
Sporophytic SI = Parent plant's genotype.
GSI is usually associated with wet stigmas, while SSI is associated with dry stigmas.

Answer 1

The Correct Option is A
