The genetic map.
Click an animal to place it at the centre and explore its family. Use the clearly labelled profile link for that animal's full record. Every line drawn here comes from a registration certificate.
Bar colour on each animal is its bloodline, and each generation is laid out in bloodline order so a line reads down the chart. An orange dot in the corner of a plate means Fire Sky owns the animal. Names and registrations are always drawn, so the map still reads with colour vision differences or in print.
Fourteen lines, fourteen colours.
Every Fire Sky line traces to a foundation cow, or to a blend of them, and is carried forward by animals whose influence made the line famous.
The portraits foreground those line icons. Select a bloodline to lay its full family out on the map, generation by generation; select it again to return to the pedigree view. The count shows how many animals in the public record carry the line.
Read it as a record.
Everything the map is showing, listed in order with sire, dam, bloodline, horn and inbreeding.
It updates as you move the map, select a bloodline or set a filter.
What the number is, and what it isn't.
It is Wright's coefficient of inbreeding, worked out from the recorded pedigree: the probability that an animal's two copies of a gene are both descended from the same ancestor. Up to and including 6.3% we call low, from there to 12.5% medium, and anything above that high. The boundaries sit where the matings do — 6.25% is what a half-sibling cross produces, 12.5% a full-brother-and-sister or parent-and-offspring one.
It is a pedigree coefficient. The earliest known ancestors, including the UMB generation, are assumed unrelated to one another. Unknown ancestors are also treated as unrelated founders. Under those assumptions the figure is Wright's coefficient for the recorded pedigree. Where an animal has no recorded parents at all, no figure is given.
