Q810
In gametophytic system of self-incompatibility, partial fertility will result from a cross between
A.
S1S2 × S1S3
AnswerB.
S1S3 × S3S4
C.
S1S2 × S2S3
D.
S2S3 × S1S2
Answer: Option A
Solution
Answer: Option A
Solution:
In the gametophytic system of self-incompatibility, partial fertility will result from a cross between S1S2 × S1S3.In gametophytic self-incompatibility (GSI), the SI phenotype of the pollen is determined by its gametophytic haploid genotype.
A fertile hermaphrodite seed plant cannot produce zygotes after self-pollination.
