Question

Quizplus · Accepted Answer

The fact that pollen from a plant with the S₁S₂ genotype is able to germinate on the stigma of another plant with the same genotype indicates that the plant is self-compatible and can self-pollinate. This is because the S₁S₂ genotype represents a plant that has both S₁ and S₂ alleles, and self-compatibility is one of the possible outcomes of possessing multiple alleles for self-incompatibility loci. Therefore, choice A is the correct answer.
