The differentiation of whorls in the flower-forming region of the plant Arabidopsis thaliana is regulated by _______ genes.
A) organ identity
B) dimer
C) whorl locator
D) caspase
E) central axis control

Question

Quizplus · Accepted Answer

Organ identity genes, such as the ABC model genes, control the differentiation of whorls in the flower-forming region by specifying the identity and fate of the floral organs. Dimer, caspase, and central axis control genes do not play a direct role in regulating whorl differentiation. Whorl locator is not a known gene or regulatory pathway involved in flower development.
