Pedigri ne demek

Purebreds are " cultivated varieties " of an animal species achieved through the process of selective breeding. When the lineage of a purebred animal is recorded, that animal is said to be " pedigreed ". Purebreds breed true-to-type which means the progeny of like-to-like purebred parents will carry the same phenotype , or observable characteristics of the parents. A group of purebreds is called a pure-breeding line or strain. 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. However, 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 improving the overall health and vigor of the breed. Because pure-breeding creates a limited gene pool , purebred animal breeds are also susceptible to a wide range of congenital health problems. Such problems also occur within certain segments of the horse industry for similar reasons. The problem is further compounded when breeders practice inbreeding. A pedigreed animal is one that has its ancestry recorded. Often this is tracked by a major registry. The number of generations required varies from breed to breed, but all pedigreed animals have papers from the registering body that attest to their ancestry. This comes from a visual analogy between the trace of the bird's foot and the three lines used in the English official registers to show the ramifications of a genealogical tree. Sometimes the word purebred is used synonymously with pedigreed , but purebred refers to the animal having a known ancestry, and pedigree refers to the written record of breeding.
