Duplication and inbreeding across the 5 generations mapped for this dog. Deterministic lineage arithmetic — nothing here is a prediction.
Inbreeding coefficientWright’s, for this dog

Ancestor loss5 mapped generations
11.9%37 distinct ancestors across the 42 positions actually filled — not the 62 theoretical slots. Higher means more duplication.
Pedigree mapped5 generations
68%42 of 62 ancestor slots are recorded.
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. 20 of 62 slots in this pedigree are still unknown, and an unknown ancestor cannot duplicate — read a low coefficient as missing evidence, never as a proven outcross.
Blood quota of double ancestors
5 generations
Ancestors holding two or more positions in this pedigree, by share of this dog’s blood within the 5 mapped generations.
S = sire sideD = dam sideG = generation
Double ancestors: blood share and recorded sire-side and dam-side positions across 5 generations. Generation 1 is the dog’s parents.
3 recorded positions. Share of the inbreeding coefficient: +2.34%.

Counts show recorded positions, not percentages. G1 = parents. A dash means no occurrence in the recorded slots; unknown ancestry remains unknown. Tap an ancestor for its coefficient contribution.
