Self-incompatibility is controlled by_________?
Correct answer: A. Multiple alleles
- A. Multiple alleles
- B. Polygenes
- C. Plasmogenes
- D. Both B and C
Explanation
Self-incompatibility is commonly controlled by a multi-allelic S locus, where pollen is rejected when its incompatibility allele matches that of the pistil. It is therefore associated with multiple alleles, not generally with polygenes or plasmogenes.
