This has interesting implications for Americans, most of whose ancestors immigrated from somewhere else; many of our ancestors also "Hybridized" or crossed with immigrants from elsewhere.
"How and When to Be Your Own Doctor"
Dr. Isabelle A. Moser with Steve Solomon
Jacob Rommel, of Morrison, Missouri, beginning work about 1860, Hybridized Labrusca and Vulpina grapes so successfully that a dozen or more of his varieties are still cultivated.

Thus, one parent of a Hybridized grape may contribute color, size, flavor and practically all the characters of the fruit, while the other parent may contribute vigor, hardiness, resistance to disease and the characters of the vine.
