Answer: Option B

Solution

Answer: Option B
Solution:
Gametophytic is the Type of Self-incompatibility observed in tomatoes.
Self-incompatibility (SI) is the ability of simultaneous hermaphrodites to avoid self-fertilization, mediated by a genetic mechanism for self-pollen recognition and rejection.
Gametophytic self-incompatibility, 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. These systems force outcrossing and maintain a wide genetic diversity.
