Only the sire side is recorded. An inbreeding coefficient needs both sides, so it is not computed here — an unmapped parent is unknown ancestry, not absent ancestry.

Pedigree mapped5 generations

50%31 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. 31 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.
