2. Both sporophytic and gametophytic controls of self-incompatibility are found in homomorphic system.
Which of the statements given above is/are correct?
A. Only 1
B. Only 2

D. None of these
Answer: Option B
Solution(By Examveda Team)
The following statements that are correct associated with self-incompatibility in crop plants are both sporophytic and gametophytic controls of self-incompatibility found in the homomorphic system.Self-incompatibility is a widespread mechanism in flowering plants that prevents inbreeding and promotes outcrossing. The self-incompatibility response is genetically controlled by one or more multi-allelic loci and relies on a series of complex cellular interactions between the self-incompatible pollen and pistil.
