Where the same dogs … May 4, 2011. Under normal circumstances if this was the only example of close breeding in a five-generation pedigree what is called the ‘inbreeding coefficient’, expressed as a percentage, would be so low as not to be significant. Through this breeding strategy, new genes are slowly introduced and unwanted genes are slowly replaced. Inbreeding is the breeding of two dogs that are very closely related to one another. High standards, diligent pedigree research and honest evaluation of the dogs the breeder is producing are also essential to guide the breeder to a successful program. Aunt to nephew, uncle to niece, half brother to half sister, and cousins are all considered line breedings. granddaughter to grandsire, uncle to niece, etc. result of an OUTCROSS Breeding. Under normal circumstances if this was the only example of close breeding in a five-generation pedigree what is called the ‘inbreeding coefficient’, expressed as a percentage, would be so low as not to be significant. Line-breeding would be pretty much anything other than the above. Line breeding is a form of inbreeding (breeding related cats to each other) that some breeders use to set characteristics in the progeny (kittens). Some people consider breeding full brothers to full sisters or fathers to daughters to be line breeding when in actuality this is called in breeding. True breeders are “tough cookies”. Say for example the female has common ancestors (say she is the result of an uncle to niece breeding), but is bred to a male with an "open" or completely outcrossed pedigree. Line breeding is when the sire and the dam are distantly related: e.g., grandsire to granddaughter, grand-dam to grandson, second cousins, half cousins, uncle to niece, aunt to nephew….. This is the most common form of breeding in purebred dogs. Through this breeding strategy, new genes are slowly introduced and unwanted genes are slowly replaced. It can double up on the best traits of the dogs, but also on the worst. Despite the risk of importing a few undesirable traits which may take a while to breed out, outcrossing can prevent a breed from stagnating by introducing fresh genes into the gene pool. In breeding dogs, in-breeding pertains to mother/son, father/daughter, brother/sister. But Becca had other plans. LINEBREEDING involves breeding relatives other than the individual parents or brothers and sisters. Line breeding is still a form of inbreeding, though it refers to more distant relationships between the breeding cats. So the average Australian Ridgeback is the product of an uncle to niece breeding. Typical linebred matings are grandfather/granddaughter, grandmother/ grandson, grandson/granddaughter, great-granddaughter/great-grandson, uncle/niece, aunt/nephew and cousin crosses. Line Breeding Line breeding is a less intensive form of inbreeding than close breeding. However, uncle-niece, aunt-nephew, half sibling matings, and first cousin matings are called inbreeding by some people and line breeding by others. The average inbreeding estimate would be 0, while the highest potential IR would be .28. With the conformation winners in the ADRK Klub Sieger Shows, all of the LINE Breedings were cousins, 1st cousins, 2nd cousins, 3rd cousins —— —— —— —— —— —— —— The benefit of line-breeding is the production of more consistent litters. The offspring will mirror the excellence of the line. [/I EVERY dog, regardless of breed, carrys at least one recessive gene. If the pup's grandfather ends up with DCM or another genetic disease, the litters odds are not good. Instead of going to college and getting a degree, she yearned to become a broodmare. Aunt-nephew and Uncle-Niece are genetically so close to that of a Mother-son or Father-daughter breeding, that any distinction is inconsequential, further muddying your distinctions of line-breeding and in-breeding. it would be considered line breeding. Another close form of breeding involves mating between grandparents and grand offspring, half siblings, uncle/aunt and nephew/niece and double first cousins. This includes, but is not limited to, cousin to cousin, aunt to nephew, uncle to niece, grandfather to granddaughter, etc. … Line breeding usually 2 - 3 generations back (grandfather to grand daughter, uncle to niece, etc) Inbreeding and linebreeding can be and has been used to improve stock and firmly cement breeding geno/phenotypes. I'd rather have the genetic diversity of 2 unrelated dogs and healthy puppies than potentially having puppies with breed faults or weakened immune system or other health problems. In the world of pedigree dogs, there is a fine line between line-breeding and inbreeding. The linebred puppies’ parents are in fact Auntie (D1) and Nephew (S2). Because inbreeding and linebreeding do not improve positively the puppies’ features, The Kennel Club decided only four years ago to outlaw and stop registering litters from a mating between mother and son, father and daughter or brother and sister. The late Pat Chenoweth (Chen Lhasa Apsos) strongly favored breeding uncle-niece or aunt-nephew to scour the gene pool, doubling strengths and pulling out qualities one might not otherwise know are lurking. This practice gives the breeder an advantage in planning future litters. Inbred animals within a specific inbred line are more likely to be alike genotypically than phenotypically for traits of economic importance. Uncle-niece, aunt-nephew, half sibling matings, and first cousin matings are called inbreeding by some people and linebreeding by others." In Hardiman's equation, he counts line breeding on either side equally. You didn’t want your lowlife cousin to come to the party, but he came uninvited with your sister. Dog breeding can be like that. Some relatives can’t be avoided. Genotype, the genetic makeup of a dog, involves the extended family. Dogs with a high COI (higher numbers) are the products of inbreeding or line breeding. *Out-Breeding* Mating of top dogs from two separate lines Through their dedication to the standards, the goal of “breed excellence” will remain firm, moving our great sport of dogs into the future. By analogy, the term is used in human reproduction, but more commonly refers to the genetic disorders and other consequences that may arise from expression of deleterious or recessive traits resulting from incestuous sexual relationships and consanguinity. However, uncle - niece, aunt- nephew, half sibling matings, and first cousin matings are called inbreeding by some people and line breeding by others. These can be identically reproduced through self-pollination for cultivation in … For breeders, it is a useful way of fixing traits in a breed—the pedigrees of some exhibition dogs show that many of their forebears are closely related. The following are universally accepted as Inbreeding: Father to Daughter; Mother to Son; Brother to Sister or Half Sister; Full Aunt to Nephew; Full Uncle to Niece. Linebreeding is a less intense form of inbreeding. How about line breeding? Inbreeding at its closest applies to what would be considered incest in human beings – parent to offspring or a mating between full siblings. Breeding to an unrelated line of the same breed (where possible) or outcrossing to another breed (where permissible) can ensure vigour. Linebreeding is a form of inbreeding and while there is no clear rule separating both terms, linebreeding commonly denotes breeding among related individuals from the same family or bloodline such as aunt to nephew, first or second cousins, uncle to niece, etc. Successful inbreeding is simply called line-breeding. Selection of breeding stock, the pedigree analysis and the styles of breeding are all tools that a breeder can use to develop his bloodline of dogs. As a general rule it is not a good idea. Breeders line breed to bring out traits, but if there are health issues behind them I'd stay clear. When line breeding, you breed together two rats who are related, but not closely. Line breeding is used for plant varieties that usually breed through self-pollination (e.g. Such plants are fertilized by their own pollen, even before they leave the flowering stage. Line breeding means breeding two animals of the same breed, within the same family. Line breeding is the mating of dogs having many common ancestors or mating to a slightly removed relative, e.g. The inbreeding rate of the father daughter breeding is DOUBLE that of an Uncle Niece. It is impossible to line breed scatter-bred dogs, but they can be inbred, i.e. mating of more distantly related animals - cousins, half brother to half sister, uncle to niece. Out-crossing Outcrossing is the mating of two dogs that are the products of line breeding but of two distinctly separate lines. This breeding is not a linebreeding it is inbreeding. However, uncle-niece, aunt-nephew, half sibling matings, and first cousin matings are called inbreeding by some people and line breeding by others. Linebreeding tends to preserve the traits of a family of dogs or bloodline while at the same time keeping a good diversity in the gene pool. That is not true. In Wright's equation, this would be considered an outcrossed pedigree. Best answers. This breeding strategy is used by breeders to create “prepotent” breeding lines that uniformly "stamp" their characteristics on their progeny. Line breeding is the mating of dogs having many common ancestors or mating to a slightly removed relative, e.g. I, as a breeder, do not recommend breeding closely related as it does introduce a higher chance of health problems and can result in smaller litter size, and weaker immune systems as well. Why Is Linebreeding In Dogs Used For? barley, wheat, oats and peas). Second-degree breeding is also a too close form for line breeding because it substantially increases the chances of getting an inherited disorder. The doubling up of favored genes with a planned result that will be replicable in future generations. *Out-Crossing* Mating of dogs from separate lines. Line breeding is like uncle to niece (I think), it has less chances (I think) of bring out heath issues. The late Pat Chenoweth (Chen Lhasa Apsos) strongly favored breeding uncle-niece or aunt-nephew to scour the gene pool, doubling strengths … This type of breeding brings certain wanted traits into a line. This is the most common form of breeding in purebred dogs. Line breeding is when the sire and the dam are distantly related: e.g., grandsire to granddaughter, grand-dam to grandson, second cousins, half cousins, uncle to niece, aunt to nephew…..
