I databasen Pawpeds kan man söka stamtavlor inom flera olika kattraser. Ett tips jag tror många missat är att för att beräkna inavelsgraden, så ska man KLICKA PÅ ordet "Inbreeding" :

"If you would like to have the inbreeding coefficient calculated as far back as there is info in the database, you can click on the word 'inbreeding'."

Då beräknas inavelsgraden för inte bara de första synliga leden utan för alla led som finns inmatade (dessa är ju ibland inte kompletta. Finns mer info om detta under User Guide/Inbreeding på Pawpeds första sida.

"Note though that this inbreeding coefficient is no more complete than the pedigree is in the database! Be sure to check if there are any ancestors missing before interpreting the meaning of any inbreeding coefficient, regardless of the number of generations it is calculated from"

How high inbreeding coefficient should we allow?

According to population geneticists the average coefficient, of all the matings we do in a breed, should increase by less than 0,25-0,5 percentage point per generation. If the increase is higher, the population will be at risk of health problems due to inbreeding. It might take many generations before the problems become visible, but when they arise they will be difficult to remove from the breed.
