Homology: A Bouquet of Broccoli One wouldn't normally munch on a rosebud or snap off a dandelion flower for a quick snack. But in fact, in terms of homologies, when you eat broccoli or cauliflower, you are doing just that. Although not scented or suitable for centerpieces, the green tips of broccoli and the white tips of cauliflower are actually flowers. Through many generations of artificial selection, farmers modified the bright yellow blooms of the wild mustard plant into the edible, vegetal plant parts you'll find nestled next to the ranch dip on the hors d'oeuvre tray. .
