calculate coefficient of inbreeding (COI) for you. The usual 3-5 generation pedigree won't give sufficient information
for a useful calculation. The best indicator for calculating inbreeding COI is 10 generations. (Going back 10
generations represents 1024 ancestors)
Modern breeders should know the COI of each of their dogs and determine what the COI will be on planned litters.
Standard Poodles average around 18%. (This is roughly equivalent to all of them being half-brothers and sisters.
Some of the tops stud dogs in the Show World average over 25% or more!) This is unacceptable!!!
Any mammal whose COI is over 6 % is inbred. |
That is very interesting. I think I will leave the inbreeding to the experts.
