# Kishu Ken (紀州犬) Nihon Ken — Kishu Ken. Breed health: 3,107 dogs, 856 founders, gene diversity 96.75%. See all Kishu Ken: https://nihonken.org/pedigree/browse?breed=kishu&format=md ## Overview A free population-genetics overview across the 3,107 Kishu Ken in the database — gene diversity, inbreeding over time, and the ancestors shaping the lines. Every figure is a floor on incomplete pedigrees: true values may be higher. ## Genetic diversity - **Dogs:** 3,107 - **Founders:** 856 - **Gene diversity:** 96.75% - **Mean kinship:** 3.25% · sampled estimate - **Effective population (Ne):** Not estimable — Mean inbreeding is not rising in the data (ΔF ≤ 0), so Ne is not estimable. Pedigree-based estimate from the rate of inbreeding, not a census Ne; a floor given incomplete pedigrees. ## Inbreeding over time Mean cached COI per birth-year cohort (1,846 dogs with a computed COI).

The modern Kishu Ken gene pool is as concentrated as if 10.2 equally used dogs had produced it. Ranked by each dog's own contribution to the 695 Kishu Ken born since 2011 with a recorded pedigree (as of 2026-10-13): the part of the modern gene pool that passes through that dog and through no dog ranked above it. The top 20 account for 79.5% of it. A dog's reach, the share of pedigrees it appears in, is a minimum: a pedigree that stops early can hide descent, never invent it. Own contributions and the effective number of ancestors are estimates from the recorded pedigrees, and can move either way as more ancestry is recorded. - **#1:** [Ichizan go (1964) · own contribution 26.5% · in 96.3% of pedigrees](https://nihonken.org/pedigree/dogs/56e76aae-b9f3-4f6e-bed8-949c7eeed9d1) -
