What is Coefficiency of Inbreeding (COI)?
Here are some links about this subject.
Basically, it is becoming evident that inbreeding
and linebreeding are not producing enough genetic diversity. The COI
number: 25% is extremely high and about as close as you can get: brother x
sister, so we are hoping to produce pups with much lower, percentages of COI.
Remember, even if you think you are outcrossing, there may be distant relatives
on both sides within 8 generations.
is a worldwide study of over 125, 000 Weimaraner pedigrees. This work is
an ongoing project by Sylvia Voorn and Menno Vlaanderen of The Netherlands.
Our appreciation to Sylvia & Menno for their excellent work.
To check out your dogs (inbred percentage or
COI) go to
Sign up for an account, search dogs, put in a dog's
name, then click on "show dog info" scroll down to find the "inbred
percentage" This will also show you the repeating relatives in the dog's
You can also do virtual matings on the website and
it will show you the inbred percentage.
