Chateau Stripmine compiles many publications without recording which one each line comes from, so its agreement counts for less than an independent genebank.

Species ancestry

Othello's ancestry is fully traced back to wild species. Depending on which source is right, between 50% and 100% is traced.

  • V. vinifera50%(0%–50%)
  • V. riparia25%
  • V. labrusca25%

How certain is the whole lineage?Covers every generation back to wild species, not just the parents: each part of the lineage counts its weakest link.Sources agree all the way: Traced to wild species through links where sources agree (or DNA confirms).Includes a disputed link: Traced through at least one link the sources disagree on.

Following every line of Othello's ancestry back to wild species: about 50% rests on sources that agree (no DNA proof somewhere); about 50% passes through a link the sources disagree on.
