Merle (coat Color In Dogs)
Merle is a genetic pattern in a dog's coat and alleles of the PMEL gene. It results in different colors and patterns and can affect any coats. The allele creates mottled patches of color in a solid or piebald coat, blue or odd-colored eyes, and can affect skin pigment as well. Two types of colored patches generally appear in a merle coat: brown/liver (red merle) and black (blue merle). Associated breeds include Carea Leonés, Australian Shepherds and Catahoula Leopard Dogs. Health issues are more typical and more severe when two merle-patterned dogs are bred together. Description Merle can affect all coat colors. The merle forms of brown are usually called "red" (though this is not correct; red and brown are genetically different), and black is called "blue" as lighter patches of black are formed throughout the coat and look slightly blue in color. Dogs who are recessive red can still be affected by merle, but the patches are either hardly seen or, if the dog is a clea ...

Welsh Corgi (Cardigan)
The Cardigan Welsh corgi (; Welsh for "dwarf dog") is one of two different varieties of livestock- herding dog breeds known as Welsh corgis (originating in Wales), with the other being the Pembroke Welsh corgi. It is one of the oldest breeds of the British Isles. Cardigan Welsh corgis are known to be an extremely loyal and trainable dog breed, naturally attuned to herding many different animals, from poultry and waterfowl to large livestock such as sheep and cattle. They are also versatile and can live in a variety of settings. History Pembroke Welsh and Cardigan Welsh corgis were both originally listed as one breed by The Kennel Club (UK) in 1925; the two varieties were officially recognized as distinct from one another by The Kennel Club by 1928, but were still categorized together under the title of "Welsh Corgis". In 1934, due to judge preferences towards each breed separately, the two breeds were finally described as uniquely different and shown separately at dog shows. T ...

Heterozygote
Zygosity (the noun, zygote, is from the Greek "yoked," from "yoke") () is the degree to which both copies of a chromosome or gene have the same genetic sequence. In other words, it is the degree of similarity of the alleles in an organism. Most eukaryotes have two matching sets of chromosomes; that is, they are diploid. Diploid organisms have the same loci on each of their two sets of homologous chromosomes except that the sequences at these loci may differ between the two chromosomes in a matching pair and that a few chromosomes may be mismatched as part of a chromosomal sex-determination system. If both alleles of a diploid organism are the same, the organism is homozygous at that locus. If they are different, the organism is heterozygous at that locus. If one allele is missing, it is hemizygous, and, if both alleles are missing, it is nullizygous. The DNA sequence of a gene often varies from one individual to another. These gene variants are called alleles. While some ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incomplete Dominance
In genetics, dominance is the phenomenon of one variant (allele) of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome. The first variant is termed dominant and the second is called recessive. This state of having two different variants of the same gene on each chromosome is originally caused by a mutation in one of the genes, either new (''de novo'') or inherited. The terms autosomal dominant or autosomal recessive are used to describe gene variants on non-sex chromosomes ( autosomes) and their associated traits, while those on sex chromosomes (allosomes) are termed X-linked dominant, X-linked recessive or Y-linked; these have an inheritance and presentation pattern that depends on the sex of both the parent and the child (see Sex linkage). Since there is only one Y chromosome, Y-linked traits cannot be dominant or recessive. Additionally, there are other forms of dominance, such as incompl ...

Crossbreeding
A crossbreed is an organism with purebred parents of two different breeds, varieties, or populations. A domestic animal of unknown ancestry, where the breed status of only one parent or grandparent is known, may also be called a crossbreed though the term "mixed breed" is technically more accurate. Outcrossing is a type of crossbreeding used within a purebred breed to increase the genetic diversity within the breed, particularly when there is a need to avoid inbreeding. In animal breeding, ''crossbreeds'' are crosses within a single species, while '' hybrids'' are crosses between different species. In plant breeding terminology, the term ''crossbreed'' is uncommon, and no universal term is used to distinguish hybridization or crossing within a population from those between populations, or even those between species. Crossbreeding is the process of breeding such an organism. It can be beneficially used to maintain health and viability of organisms. However, irresponsible crossbre ...

Purebred Dog
A dog breed is a particular type of dog that was purposefully bred by humans to perform specific tasks, such as herding, hunting, and guarding. Dogs are the most variable mammal on Earth, with artificial selection producing upward of 360 globally recognized breeds. These breeds possess distinct traits related to morphology, which include body size and shape, tail phenotype, fur type, etc., but are only one species of dog. Their behavioral traits include guarding, herding, and hunting, and personality traits such as hyper-social behavior, boldness, and aggression. Most breeds were derived from small numbers of founders within the last 200 years. As a result of their adaptability to many environments and breedability for human needs, today dogs are the most abundant carnivore species and are dispersed around the world. A dog breed will consistently produce the physical traits, movement and temperament that were developed over decades of selective breeding. For each breed they re ...

Breed Standard
In animal husbandry or animal fancy, a breed standard is a description of the characteristics of a hypothetical or ideal example of a breed. The description may include phenotype, physical or morphology (biology), morphological detail, genotype, genetic criteria, or criteria of athletic or productive performance. It may also describe faults or deficiencies that would disqualify an animal from registration or from animal reproduction, reproduction. The hypothetical ideal example may be called a "breed type". Breed standards are devised by breed associations or breed clubs, not by individuals, and are written to reflect the use or purpose of the species and breed of the animal. Breed standards help define the ideal animal of a breed and provide goals for breeders in improving stock. In essence a breed standard is a blueprint for an animal fit for the function it was bred - i.e. herding, tracking etc. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conformation Show
A dog show is an animal show; it is an event where dogs are exhibited. A conformation show, also referred to as a '' breed show'', is a kind of dog show in which a judge, familiar with a specific dog breed, evaluates individual purebred dogs for how well the dogs ''conform'' to the established breed type for their breed, as described in a breed's individual breed standard. Dog shows can be in the means of evaluating dogs for breeding purposes. A conformation championship from a recognised national kennel club is generally considered as an indication of merit. Many breeders consider championships a prerequisite for breeding. Some critics argue that the shows can encourage selective breeding of traits and lower genetic diversity. The first modern conformation dog show was held in Newcastle Town Hall in Newcastle upon Tyne, England, in June 1859. Judging A conformation dog show is not a comparison of one dog to another but a comparison of each dog to a judge's mental imag ...

Breed Registry
A breed registry, also known as a herdbook, studbook or register, in animal husbandry, the hobby of animal fancy, is an official list of animals within a specific breed whose parents are known. Animals are usually registered by their breeders while they are young. The terms studbook and register are also used to refer to lists of male animals "standing at stud", that is, those animals actively breeding, as opposed to every known specimen of that breed. Such registries usually issue certificates for each recorded animal, called a pedigree, pedigreed animal documentation, or most commonly, an animal's "papers". Registration papers may consist of a simple certificate or a listing of ancestors in the animal's background, sometimes with a chart showing the lineage. Types of registries There are breed registries and breed clubs for several species of animal, such as dogs, horses, cows and cats. The ''European Association of Zoos and Aquaria'' (EAZA) and the US '' Association of Zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Dane
The Great Dane is a German list of dog breeds, breed of large mastiff-sighthound, which descends from hunting dogs of the Middle Ages used to hunt bears, wild boar, and deer. They were also used as guardian dogs of German nobility. It is one of the two largest dog breeds in the world, along with the Irish Wolfhound. History In the sixteenth century the nobility in many countries of Europe imported strong, long-legged dogs of different sizes and phenotypes, some of mastiff or greyhound type, from England and Ireland.Ludwig Beckmann (1895)''Geschichte und Beschreibung der Rassen des Hundes'' Volume 1, p. 6 (in German) These dogs were called ''Englische Docke'' or ''Englische Tocke'' – later written and spelled: ''Dogge'' – or ''Englischer Hund'' in Germany. The name simply meant "English dog". Since then, the English word "dog" has come to be associated with a molossoid dog in Germany and France. These dogs were bred in the courts of German nobility, independent of the Eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beauceron
The Beauceron () is a herding dog breed originating from the plains of Central France. The Beauceron is also known as Berger de Beauce (, sheepdog from Beauce) or Bas Rouge (, red-stockings). Description Appearance This breed stands in height and weighs The Beauceron has a hard outer coat and a woolly undercoat that grows thick in cold weather, especially if the dog sleeps outdoors. Its standard colouring is black and tan (the latter colour referred to in French as ''rouge ecureuil'', squirrel-red) or, less frequently, grey, black and tan called harlequin. Other colours, such as the once prevalent tawny, grey or grey/black, are now banned by the breed standard. The harlequin coats should have more black than gray with no white. In the black and tan dogs the tan markings should appear in two dots above the eyes, on the sides of the muzzle, fading off to the cheeks, but do not reach the underside of the ears. Also on the throat, under the tail and on the legs and the chest. Tan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
