Solution(By Examveda Team)
The gametophytic system of self-incompatibility was first reported in Nicotiana sanderae.Gametophytic self-incompatibility is a type of self-incompatibility that was first described by east and mangeldorf in 1925 in tobacco.
In this system, the incompatibility reaction of pollen is determined by its genotype and not by the genotype of the plant on which it is produced.
It involves the inability of the gametes from the same parent plant to fuse and form a zygote or, if the zygote forms, then it fails to develop.
