Q822
In gametophytic system of self-incompatibility, fully compatible will result from a cross between
A.
S1S2 × S1S3
B.
S1S2 × S3S4
AnswerC.
S1S2 × S1S2
D.
S3S4 × S2S1
Answer: Option B
Solution
Answer: Option B
Solution:
In the gametophytic system of self-incompatibility, fully compatible will result from a cross between S1S2 × S3S4.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.
The fully compatible progeny will result from a cross between S1S2 × S3S4.
