The information I posted is from
http://www.bengal-data.com. Bengalpedigrees.com does not have all of this information.
Every bengal has multiple ALCs in their pedigree. When you start back from 2 parents, 4 grandparents, 8 great-grand parents, etc., you can end up with hundreds of different cats in the pedigree. When it come to Orion, yes, he has 9 ALCs from the dam side and 7 from the sire side. Many are the same. What Bengal Data does is take every cat in Orion's pedigree back to the ALC. They post the F generation for each of the ALCs and, naturally, the lowest generation shown is the one for your cat. Taro of Bundas is the ALC that makes your Orion an F7. You always use the shortest route back to the ALC.
As for the co-efficiency inbreeding -- It is a complicated formula. Unfortunately, the bengal breed started with a very limited pool of cats. The imbreeding started with Jean Mill. She had to breed Millwood Destiny (F3) back with his mother, Millwood Praline (F2).
For Orion, this is what I found:
COI Calculation for AWAGATI ORION
Total COI is: 34.5%
common: 18 possible: 62 available: 62 effective: 44 => AVK: 29.032%
COI@5 Gens => 14.258%
8.008% through AWAGATI ROSE TATOO (1 path)
6.250% through AMANTRA CHIAROSCURO (1 path)
What I'm interpreting is there is 14.258% inbreeding in the last five generations. Is this good or bad? I don't know. My Raiden has 25% co-efficiency with 0% in the previous five generations. Meaning, no cat repeats within the 64 cats.
Most bengal owners are not interested in this information. Bengal breeders should be. I have seen TICA pedigrees where the cats are bred over and over again on the sire and the dam side. This is not good for the breed and health of these cats.
