'', the dorsal (upper or adaxial) part of the flower expresses one or more genes in the ''Cycloidea'' (''CYC'')/''Dichotoma'' (''DICH'') family. In ''Cadia'', these genes are expressed throughout the flower. Thus, from a molecular point of view, ''Cadia'' is not reversing the ancestral evolution from radial symmetry to bilateral symmetry, but obtaining radial symmetry from a new mechanism.
