The development of these structures is described as the interaction of three groups of homeotic genes in the ABC model. Entomophilous (“en-toh-MOFF-il-us”) examples of these structures (-5[1])co-evolved ultraviolet patterns (10[1])to advertise themselves. (10[1])The ability to bear fruits and these structures is shared by all (10[1])angiosperms, (10[1])whose common name references these structures.
