Merle (dog coat) 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 ...
Eye color. Eye color is a polygenic phenotypic trait determined by two factors: the pigmentation of the eye 's iris [1][2] and the frequency-dependence of the scattering of light by the turbid medium in the stroma of the iris. [3]: 9. In humans, the pigmentation of the iris varies from light brown to black, depending on the concentration of ...
The coat of the domestic dog refers to the hair that covers its body. Dogs demonstrate a wide range of coat colors, patterns, textures, and lengths. As with other mammals, a dog's fur has many uses, including thermoregulation and protection from cuts or scratches; furthermore, a dog's coat plays an important role in the showing of purebred dogs.
The link between merle coats and eye color doesn’t explain why Siberian Huskies can have some of the bluest eyes around. But Embark, another company studying dog DNA, may have found an answer.
In dogs, the Liver color is caused by dilution of the eumelanin (black) pigment by the B locus. The gene that causes Liver is recessive, so a BB or Bb dog has normal black pigment. Only a bb dog is Liver. There are several different recessive b genes, but they all turn the coat brown. They are only distinguishable through genetic testing. [ 2 ]
A wire-haired dachshund. A typical dachshund is long-bodied and muscular with short stubby legs. Its front paws are disproportionately large, being paddle-shaped and particularly suitable for digging. Its skin is loose enough not to tear while tunneling in tight burrows to chase prey. Its snout is long.
Displayed in the adjacent table is the color rich maroon, i.e. maroon as defined in the X11 color names, which is much brighter and more toned toward rose than the HTML/CSS maroon shown above. See the chart Color name clashes in the X11 color names article to see those colors that are different in HTML/CSS and X11.
Heterochromia iridum. Heterochromia is a variation in coloration most often used to describe color differences of the iris, but can also be applied to color variation of hair [1] or skin. Heterochromia is determined by the production, delivery, and concentration of melanin (a pigment). It may be inherited, or caused by genetic mosaicism ...
