Located in Central Louisiana, Charolais Golden Retrievers breeds a few litters a year. Our Sire is 100% American with Champion bloodlines. Our Dams are 50% American and 50% English with AKC Champions & European Champions Close up in their pedigrees, These crosses on lineage results in a very low C.O.I
(Coefficient Of Inbreeding) resulting in very healthy beautiful puppies.
What is COI?
COI stands for Coefficient of Inbreeding. Essentially, it measures the common ancestors of dam and sire, and indicates the probability of how genetically similar they are.
Why should I care?
There are consequences to being genetically similar, some good, some bad. The fact that dogs within individual breeds are so genetically similar is what makes them that breed- and why , if you breed any Golden Retriever to any other Golden Retriever, the puppies will look recognizably like Golden Retrievers.
OK, go on…but please keep it simple..
Many of the 20,000-odd genes that go into any dog of a particular breed are ‘fixed’. That means that every Golden will have two identical copies of them- one inherited from their dam; one from their sire. Others however, are not so fixed.
Genes always come in pairs. The gene-pair is called an ‘allele’. When the pair is identical, it is called ‘homozygous’. When the pair is not identical, it is called ‘heterozygous.’
‘Allele’, ‘homozygous’ and ‘heterozygous’ are three good words to understand if you are a dog breeder. Homozygous and heterozygous are terms often used more generally, too, when talking about diversity. The more gene-pairs that are homozygous = less diversity. The more gene-pairs that are heterozygous = more diversity. Geneticists in the main consider diversity a good thing.
