What is an Inbreeding coefficient? It is a measure of how close two individuals are genetically related to each another. The coefficient of inbreeding, symbolized by the letter F, is the probability that an animal with two identical genes received both genes from one ancestor. Take a first-cousin mating. First cousins share a set of grandparents. Inbreeding is the mating of animals that are closely related to each other. Outcrossing is the mating of animals that are totally unrelated.
Welfare problems can occur where the immune system is compromised. By mating unrelated parents, there is a significant reduction in the risk of the offspring suffering from an inherited disorder. What is inbreeding? What is close inbreeding? What is linebreeding? Why should inbreeding be avoided? This is the Korthals griffon, named after its creator, Eduard Korthals. Born into a wealthy Dutch family, in , at the age of 22, Korthals set out to create his own all-round shooting dog.
He started with seven pointing griffons and then carefully line-bred until he succeeded in producing the sort of dog he was aiming for. It took him 20 years to achieve his goal.
The result: a dog that Korthals called the wirehaired pointing griffon, the name by which it continues to be known in the US. He bred more than but kept just Today the breed is most numerous in France, while its popularity is growing in the UK. It says a lot about the dogs that Korthals selected that the breed remains as healthy as it is today. However, because it has remained a hunting dog Continental breeders have concentrated on health and ability rather than looks. This greatly increases the chances of genetic defects and hereditary diseases being passed on to successive generations.
Perhaps someday we may have to use outcross techniques to restore genetic diversity. If we do, hopefully we will still be able to retain the positive characteristics of this most incredible breed of canine.
