Estimate Wright’s coefficient of inbreeding for a planned litter. Enter the queen and sire, expand parents, and mark the same ancestors by reusing them — not by spelling alone.
Enter names for the queen and sire to see offspring COI.
COI is a pedigree statistic (Wright’s method), not a DNA test. Blank slots count as unrelated — an incomplete tree understates the figure. Registries may count deeper. It does not replace type, temperament, or health testing.
