# Trial mating

Project a hypothetical litter's inbreeding (COI) and its parents' relationship (COR) for any sire and dam. Nothing is saved — the URL is the result.

## How to run one
Name the sire and dam by id in the URL: https://nihonken.org/pedigree/trial-mating?sire={sireId}&dam={damId}&format=md — dog ids come from search (https://nihonken.org/pedigree/browse?q=NAME&format=md).

## What comes back
- **Litter COI:** the projected coefficient of inbreeding — a floor (≥) when the pedigree is incomplete
- **Parent relationship (COR):** how related the sire and dam are
- **Shared ancestors:** the dogs behind both parents that drive the COI
