Phenotypes of Some Crops and
Their Progenitors
A plant of the maize progenitor,
teosinte (left), with multiple
stalks and long branches, is
shown next to a plant of
cultivated maize (right) with its
single stalk. A maize ear (inset)
bears its grain naked on the
surface of the ear, whereas a
teosinte ear (inset) has its grain
(not visible) enclosed in the
triangular casing that comprises
the ear
