A cryptic merle is one with such small patches of merling, or none at all, that it appears to be a non-merle. [16] This is commonly seen in dogs who are recessive red, clear recessive reds in particular, though patches can still be seen in certain red dogs. [17] In America, a dog with the phantom merle coloring is sometimes described as being ...
Great Danes also may carry the merle gene, which is part of the genetic makeup that creates the harlequin coloring. [35] The merle gene is an incomplete dominant, meaning only one copy of the gene is needed to show the merle coloring; two merle genes produce excessive white markings and many health issues such as deafness, blindness, or other ...
In 2018, a genetic study found that just prior to 1859 a broadly distributed European herding dog had given rise to the German Shepherd Dog, the French Berger Picard, and the five Italian herding breeds: the Bergamasco Shepherd, Cane Paratore, Lupino del Gigante, Pastore d'Oropa, and the Pastore della Lessinia e del Lagorai.
Little Boo, a therapy dog assigned to Big Boo in Orange Is the New Black, is a Labrador; Merle is a Lab mix featured in Ted Kerasote's book Merle's Door. It follows the life of the dog that Kerasote found on a canoe trip in the Tetons, until Merle's passing and the dog's free range life in a small Wyoming town.
When a dog has wild-type alleles at all three genes, it will have a yellow coat. When the dog has a loss-of-function allele at MC1R, it will have a yellow coat regardless of the genes it carries on the other two genes. Only a dominant black allele at CBD103 will produce a black coat color in dogs possessing wild-type alleles at MC1R and Agouti. [8]
The Old English Sheepdog is a large breed of dog that emerged in England from early types of herding dog. Other names for the breed include Shepherd's Dog and bob-tailed sheep-dog . [ 1 ] The nickname Bob-tail (or Bobtail ) originates from how dogs of the breed traditionally had their tails docked .
Dogs display wide variation in coat type, density, length, color, and composition. Dogs have a wide range of coat colors, patterns, textures and lengths. [1] Dog coat color is governed by how genes are passed from dogs to their puppies and how those genes are expressed in each dog.
[2] [4] [3] The modern breed is predominantly bred for pets; despite this, many retain a strong herding instinct and it is not uncommon for companion dogs of the breed to try to herd children or other pets. [2] [5] A very active breed, the Australian Shepherd is known to become destructive if it does not receive adequate exercise. [2] [5]
