Q147
In gametophytic system of self-incompatibility fully incompatible will result from a cross between
A.
S1S2 × S1S2
AnswerB.
S1S2 × S3S4
C.
S1S2 × S1S3
D.
S3S4 × S2S1
Answer: Option A
Solution
Answer: Option A
Solution:
In the gametophytic system of self-incompatibility fully incompatible will result from a cross between S1S2 × S1S2.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.
