Confirmation that the S gene was responsible for self-incompatibility came from
A) overexpression of a plant's usual allele of the S gene.
B) expression of a foreign S gene.
C) homologous recombination knocking out expression of the S gene.
D) microarrays showing expression patterns of the S gene.
E) RT-PCR showing expression patterns of the S gene.

Question

Quizplus · Accepted Answer

Expression of a foreign S gene would allow researchers to determine whether or not it is responsible for self-incompatibility. If expression of the foreign S gene leads to self-incompatibility, it would confirm that the S gene is responsible for this trait.
