Thoroughbred pedigree analysis and racing on Android.
Bloodline is an Android app for thoroughbred pedigree analysis: repeated ancestors, inbreeding coefficient and hypothetical matings. It includes a game that breeds and races horses from real pedigrees.
Pedigree analysis
- Inbreeding coefficientWright's coefficient over eight generations, with the share of the pedigree known.
- Repeated ancestorsAncestors on both the sire and dam side, in standard notation (3×4, 4×5×5), with each one's share of the total.
- Hypothetical crossesAny stallion × any mare: the foal's pedigree and inbreeding. Galileo × Kind returns Frankel's figures.
- Pedigree treeFive generations; each ancestor opens its own pedigree.
Breed and race horses with real ancestry
The game breeds foals from the same pedigree graph the analysis uses. In development.
Real ancestry
Game horses descend from real thoroughbred bloodlines and carry the same inbreeding and cross analysis.
Free to play
Play with in-game money, or pay for more. In-game money is never sold, has no cash value and cannot be cashed out. There are no real-money prizes.
One app
The analysis and the game share one pedigree engine and one install.
