In the ABC model of floral organ determination in Arabidopsis, the expression of class Agenes alone determines the development of sepals, expression of class A genes along with class B genes determines petal formation, expression of class B genes along with class C genes determines the formation of stamens and expression of class genes alone determines carpel formation. Loss of class B gene function would result in flowers with whorls in the following order (from outer whorl to inner whorl)
