Are Inbreeding and Line Breeding the same?

Answer 1

Depends.

Inbreeding is generally considered to be first level relatives being bred to one another... Father to daughter, sister/brother, mother/son

Linebreeding is generally highly related dogs being bred together- dogs with the same grandparent(s) or great great grandparent(s).

However, genetically speaking.... if you have a wide open pedigree with no real linebreeding or inbreeding for 10 generations and you decide to inbreed (assuming you know the genetic issues) the resulting pups can have a lower COI (coefficiency of inbreeding) than a tightly linebred pup whose pedigree is based on combining the same set of genetics over and over.

So, a linebred dog can technically be more inbred than a dog produced by inbreeding.

In both cases you have to have indepth knowledge regarding the genetic ick in the breed and in the pedigree of the animals you're dealing with. You have to be a bit of a gambler and RUTHLESS about eliminating any dog with any HINT of an issue genetically from your breeding plans.

Answer 2

Somewhat. In both cases you are breeding related dogs to each other. It is just a matter of how closely related. With inbreeding you are using more closely related dogs. There is no true cut off that says this is line breeding and this is inbreeding so it can be a bit of a judgment call. Honestly neither is good or bad, it all depends on the quality of the dogs that are being used. It is just that the closer related the dogs are the more likely you are to have recessive genes express themselves. By the same token doing a total outcross (the dogs are totally unrelated) does not guarantee that you will avoid those hidden recessive genes. I once did an outcross breeding where the sire and dam had no common ancestors until the 5 generation and still had a recessive color pattern show up. In this case it was only a non-preferred color but in some cases a simply recessive can cause genetic disorders that end up in blindness, deafness and other harmful conditions.

Answer 3

No, inbreeding is breed dogs from the same "immediate" family, father/daughter, mother/son, brother/sister, etc. This type of breeding is often detrimental because the dogs have too limited of a variety of genetics, they are too closely related and either have come from the same breeding or have passed on their own genetics into the other part of their pair. Line breeding is breeding within the same extended family or same "line", for example, breeding dogs with the same grandsire or great-grandsire. They are not as directly related giving them some genetic variability, but they have the same genetic background, which can improve breeding stock by ideally strengthening those characteristics which are desired.

Answer 4

eDepends on who you ask - the technical definition of inbreeding is breeding two animals more closely related than the breed average. Linebreeding by this definition is a form of inbreeding that keeps the relationship to an ancestor high while keeping the COI low. The COMMON use of these terms among dogbreedrs is determined by relationship of the parents very close (sibling or parent/child) it inbreeding more distant (cousins) is linebreeding. Then there is the cynical joking definition -they call it linebreeding when it works (produces good projeny), inbreeding when it doesn't.

PS COI is a statistical "relationship" test that takes in account ll relationships between parents for several genations

Answer 5

No inbreeding is taking a mother/son or father/ daughter and even brother/sister and breeding that way~Line breeding is taking the best of the distant family in that breeding line and breeding them to get better dogs. Puppy mills and fly by night breeders will use the inbreeding to get the highest amount of dogs while good breeders will do line breeding to get the highest quality of dogs. Please check out all breeders and what their breeding standars are before you get a puppy.

Answer 6

Not really. Although both involve the breeding of related dogs, inbreeding involves closely related dogs (i.e. sire/daughter, littermates, etc.) and line breeding involves dogs with a common ancestor such as a grandparent, so it is not as close, and there is more genetic diversity than there is similarity.

With inbreeding, you concentrate the genes of those two individuals, for better or for worse. With linebreeding, you are trying to concentrate the genes of a relative a couple of generations back.

Most breeders with knowledge of their breed/bloodlines will linebreed. Inbreeding poses more potential problems, and should only be done by someone very certain of the pedigree they are dealing with...certainly not the backyard breeder or novice.

Answer 7

Not entirely. Inbreeding in dogs is typically breeding with a parent and possibly a full sibling (not considered a good breeding practice). Line breeding is breeding with a related individual (cousin, for example). This is done at times to enhance a specific desirable trait and is a more common breeding practice.

Answer 8

It's a matter of degree. Most breeders use the term "inbreeding" when the dogs are very closely related and "line breeding" when it is a more distant relationship.

Answer 9

Matter of opinion. If you are related you are related.

Breeders started using the term Line Breeding to get away from the term Inbreeding.

No,
Line breeding is 2 dogs that are closely related like cousins and inbreeding is brother sister, mother son type of breeding.
