Using just the 'ABC model' of floral development what would you need to change in terms of genes or gene expression to get male only flowers, but still have 3 different floral whorls in total?  Then what would you need to change to get female flowers and again have three different floral whorls in total?
In some species, such as magnolia, sepals look like petals, and both are collectively called "tepals:' Suggest an extension to the ABC model that could hypothetically account for the origin of tepals.
