Every figure is a floor on incomplete pedigrees: true values may be higher. ## Genetic diversity - **Dogs:** 5,946 - **Founders:** 2,060 - **Gene diversity:** 99.46% - **Mean kinship:** 0.54% · sampled estimate - **Effective population (Ne):** 238 (pedigree estimate · Ne = 1/(2·ΔF), with ΔF read from the least-squares slope of mean COI over birth year, scaled to per-generation by an assumed 4-year generation interval and standardized over the remaining diversity (1 − F_baseline).) ## Inbreeding over time Mean cached COI per birth-year cohort (1,326 dogs with a computed COI).
