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
0.00%No shared lineage within the mapped generations
Ancestor loss5 mapped generations
8.3%44 distinct ancestors across the 48 positions actually filled — not the 62 theoretical slots. Higher means more duplication.
Pedigree mapped5 generations
77%48 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. 14 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.
2 recorded positions. No contribution to the inbreeding coefficient is recorded for this ancestor in this window.

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.
