A pedigree chart is a diagram that shows the occurrence of certain traits through different generations of a family, [1] [2] most commonly for humans, show dogs, and race horses. [ citation needed ] Definition
In the world of selective animal breeding, to "breed true" means that specimens of an animal breed will breed true-to-type when mated like-to-like; that is, that the progeny of any two individuals of the same breed will show fairly consistent, replicable and predictable characteristics, or traits with sufficiently high heritability.
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.
In this pedigree chart, G is the progeny of C and F, and C is the biological uncle of F. To find the coefficient of inbreeding of G, first locate a loop that leads from G to the common ancestor through one parent and back down to the other parent without going through the same individual twice.
Domestic dogs are phenotypically diverse mammals shown by differences in morphology and behavior across different breeds. [23] Factors that contribute to this diversity are reproductive isolation, bottlenecks, and genetic drift. Data collected through owner reports suggests that genetic diversity has an effect on dogs' lifespan.
Pedigree chart, a document to record ancestry, used by genealogists in study of human family lines, and in selective breeding of other animals Pedigree, a human genealogy (ancestry chart) Pedigree (animal), a breed registry Purebred, or "pedigreed" animal with a recorded lineage
The education of fish biologists paid less attention to quantitative genetics and breeding plans. [25] Another was the failure of documentation of the genetic gains in successive generations. This in turn led to failure in quantifying economic benefits that successful selective breeding programs produce.
For example, the dog that won the 2008 Westminster show (US) was named K-Run's Park Me In First, with the call name of "Uno". [9] Dogs in the breed registry of a working dog club (particularly herding dogs) must usually have simple, no-nonsense monikers deemed to be "working dog names" such as "Pal", "Blackie", or "Ginger". The naming rules for ...
