A classical pedigree represents the descendants of a person or other living being and is part of genealogy (genealogy). In this form the descent "of all" varieties or even less represent is impossible and fails for several reasons. The diplomologist Andreas Young note the following: There are many individual Parent-offspring relationships but no real pedigrees, as often only the mother is clear and the father is missing, as with the numerous seedlings of the Gouais blanc (White Heunisch). Every seed in a berry is in principle a potential new grape variety, but it only becomes this when the nucleus gets into the soil, germinates there and then grows into a vine. Within a berry with 5 to 6 seeds, the fathers can be 5 to 6 varieties, depending on what pollen at the blossom was used.
