Quizplus · Accepted Answer

The S1S2 genotype indicates that the plant has both S1 and S2 alleles, which means that it is self-compatible and can self-pollinate. Therefore, option A is the correct answer. Option B is incorrect because self-compatible plants do not necessarily have to cross-pollinate. Option C is incorrect because self-incompatible plants cannot self-pollinate. Option D is incorrect because self-incompatible plants may still be able to self-pollinate if they have the appropriate genotype.
