The condition of maturation of anthers and stigmas of the same flower simultaneously is
What is pre-requisite for self pollination?
The condition of maturation of stigma before anthers of the same flower is
Assertion (A): Self ineompatibility is not an absolute phenomenon.
Reason (R): Even highly self-incompatible species can be self-pollinated by one stratagem or another.
Consider the following with reference to sporophytic (SSI) or gametophytic (GSI) self-incompatibility systems:
1. SSI-3 celled pollen, rejection reaction on the stigma
2. GSI -2 celled pollen, rejection reaction in the style. SSI -2 called pollen, rejection reaction in the style.
3. GSI- 3 celled pollen, rejection reaction on the stigma
Which of these features are correct in the case of sporophytic gametophytic self- incompatibility systems?
