Thistledown WarrenGran's Ledger
Build a pedigree up to five generations. The ledger works out the inbreeding figure the game uses, and how likely each rabbit is to carry a hidden gene, from what you know about it and its family.
Tap a rabbit, or an empty space, to fill it in.
How the odds are worked out
Each rabbit starts from what you've seen of it: a gene it shows, or a "?". A rabbit with no parents in the ledger gets the game's own odds for how common each version is. A rabbit with parents gets the mix its parents could pass on. Then the game's own rule for litters runs upwards: a rabbit showing a hidden version (two copies) means both its parents carry it. If the same rabbit appears twice, mark it as the same rabbit so the inbreeding counts it.
This is a guide, not a lab test: it reads the family downwards and uses the litter rule upwards, which is how the game reasons too.
