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:** 96.79% - **Mean kinship:** 3.21% · 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 (1,699 dogs with a computed COI).
