Solution (By Examveda Team)

In the sporophytic system of self-incompatibility, full fertility will result from a cross between S₂S₃ × S₁S₂.
Sporophytic self-incompatibility (SSI) is a self-pollen recognition system that enforces outcrossing in plants.
Recognition in SSI systems is typically controlled by a complex locus (S-locus) with separate genes that determine pollen and stigma specificity.
