Q818

Self incompatibility seen in cole crops is

A.
Gametophytic
B.
Sporophytic
Answer
C.
Genetic
D.
Heterostylic

Answer: Option B

Solution

Answer: Option B
Solution:
Self-incompatibility seen in cole crops is Sporophytic.
Self-incompatibility, the recognition and rejection of self-pollen, is a widespread mechanism by which flowering plants prevent self-fertilization.
In the Brassicaceae (cole crops), the self-incompatibility phenotype of both stigma and pollen is determined sporophytically by the diploid S-locus genotype of the parent plant and dominance relationships between S-locus variants are observed in both stigma and pollen.
