It developed an online tool called Mate Select, which allows people to look up health test results and inbreeding level of individual dogs compared to the breed average. The database can also calculate for breeders the coefficient of inbreeding (COI) that two selected dogs will produce. A father/daughter mating will produce puppies with a COI ...
Line breeding is differentiated from inbreeding by excluding pairings between parents and offspring, and between full siblings. Outcrossing is the planned breeding between two unrelated dogs, used to increase genetic diversity in a breed and decrease genetic issues or abnormalities inherited from line breeding or inbreeding.
The Japanese Medaka fish has a high tolerance for inbreeding, one line having been bred brother-sister for as many as 100 generations without evidence of inbreeding depression, providing a ready tool for laboratory research and genetic manipulations. Key features of the Medaka that make it valuable in the laboratory include the transparency of ...
Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. [1] 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 recessive traits resulting from ...
The programme analyses that dogs were initially bred for practical functions such as hunting and guarding, but in the middle of the 19th century, breed standards began to shift, as dogs became a status symbol and dog breeding became a sport, and the function of a dog became a secondary consideration after appearance.
Outcrossing can be a useful technique in animal breeding.The outcrossing breeder intends to remove the traits by using "new blood." With dominant traits, one can still see the expression of the traits and can remove those traits, whether one outcrosses, line breeds or inbreeds.
Breeding from too small a gene pool, especially direct inbreeding, can lead to the passing on of undesirable characteristics or even a collapse of a breed population due to inbreeding depression. Therefore, there is a question, and often heated controversy, as to when or if a breed may need to allow "outside" stock in for the purpose of ...
Animal breeding is a branch of animal science that addresses the evaluation (using best linear unbiased prediction and other methods) of the genetic value (estimated breeding value, EBV) of livestock. Selecting for breeding animals with superior EBV in growth rate, egg, meat, milk, or wool production, or with other desirable traits has ...
