Relative Relationships Chart

How to Use the Chart

  • Identify the pair's most recent common ancestor. Example: To identify the relationship between Ezekiel de le Poer and Barrett Poer de Aika XIII, we look on the family tree and see their most recent common ancestor is Nosferatu Traum.
  • Find the first party's relationship to the common ancestor; select that row. Example: Nosferatu is Ezekiel's Great Great Grandfather--select the row (Great)2 Grandchild.
  • Find the second party's relationship to the common ancestor; select that column. Example: Nosferatu is Barrett's Great Great Great Grandfather--select the column labeled (Great)3 Grandchild.
  • Where the column and row intersect tells you the relationship between the original pair. Example: The (Great)2 Grandchild row and the (Great)3 Grandchild column's intersection reveals that Barrett and Ezekiel are 3rd cousins, 1x removed.
  • The percentage indicates the approximate amount of shared genetic material. Example: Although Barrett and Ezekiel are related, they share less than half a percent of the same genes.

Notes

  • This chart does not account for identical twins or inbreeding. Identical twins share 100% of their genes, so their children (who would be cousins) would share more like 25% of their genes instead of the listed 12.5%. Inbreeding could also increase the amount of shared genetics, albeit in a more complicated way.
  • The percentages here refer to shared allosomal (or sex) chromosomes only (i.e. X and Y chromosomes). All canines likely share over 99% of their autosomal DNA: "There is very little genetic difference between any dog and any wolf, coyote, or jackal, etc., so little, in fact, that genetic tests cannot tell how much wolf is in deliberately bred wolf-dogs."
  • If you're confused by all that jibber-jabber, don't worry! The key point here is anyone more distant than, say, a third cousin will share overwhelmingly little of the same genes.
