Line-breeding detail — ancestors on both sides
Duplication and inbreeding across the 5 generations mapped for this dog. Deterministic lineage arithmetic — nothing here is a prediction.
Computed from the identified parent links recorded in this 5-generation window, including shared ancestors’ recorded inbreeding. Unknown founders are assumed unrelated; this is not a DNA measurement or certification of the source records. Displayed percentages are rounded. Every slot in this pedigree is recorded across this window; records that run deeper than 5 generations are still outside it.
Ancestors holding two or more positions in this pedigree, by share of this dog’s blood within the 5 mapped generations.
