## Overview
A free population-genetics overview across the 5,946 Akita Inu 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:** 5,946
- **Founders:** 2,060
- **Gene diversity:** 99.46%
- **Mean kinship:** 0.54% · sampled estimate
- **Effective population (Ne):** 122 (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 (3,153 dogs with a computed COI). Population means, not individual COIs.

## Most influential dogs
Effective number of ancestors: 86.7. The modern Akita Inu gene pool is as concentrated as if 86.7 equally used dogs had produced it. Ranked by each dog's own contribution to the 1,962 Akita Inu born since 2011 with a recorded pedigree (as of 2026-10-16): the part of the modern gene pool that passes through that dog and through no dog ranked above it. The top 20 account for 37.3% 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.
