Solution(By Examveda Team)

In the gametophytic system of self-incompatibility, partial fertility will result from a cross between S₁S₂ × S₁S₃.
In gametophytic self-incompatibility (GSI), the SI phenotype of the pollen is determined by its gametophytic haploid genotype.
A fertile hermaphrodite seed plant cannot produce zygotes after self-pollination.
