Pedigree analyses

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: 2.34%Slight line-breeding within the mapped generations
Ancestor loss5 mapped generations: 14.5%53 distinct ancestors across the 62 positions actually filled — not the 62 theoretical slots. Higher means more duplication.
Pedigree mapped5 generations: 100%62 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. Every slot in this pedigree is recorded across this window; records that run deeper than 5 generations are still outside it.
