The Dexter is an Irish breed of small cattle. [6] It originated in the eighteenth century in County Kerry , in south-western Ireland, and appears to be named after a man named Dexter, who was factor of the estates of Lord Hawarden on Valentia Island .
"The Genetics of Equine Coat Color" Texas A&M University Department of Animal Science Equine Sciences Program, publication HRG-003 (undated). The same group of researchers found that the WW gene complex was also lethal in Dexter cattle, platinum foxes, and bluefrost minks.
Roan is a coat color found in many animals, including horses, cattle, antelope, cats and dogs. It is defined generally as an even mixture of white and pigmented hairs that do not "gray out" or fade as the animal ages. [1] There are a variety of genetic conditions which produce the colors described as "roan" in various species. Bay Roan with ...
[1]: 48 [2]: xxii, 127 A similar colour pattern is seen in the domestic yak [1]: 48 and in some zebuine cattle. [ 3 ] An extreme pale form of the colour-sided pattern is the colour-pointed or 'white park' pattern, seen for example in the White Park , the British White and in some Irish Moiled , where the darker colour is restricted to the ears ...
Cattle breeds fall into two main types, which are regarded as either two closely related species, or two subspecies of one species. Bos indicus (or Bos taurus indicus ) cattle, commonly called zebu, are adapted to hot climates and originated in the tropical parts of the world such as India, Sub-saharan Africa, China, and Southeast Asia.
An American breeder, Richard Gradwohl, has developed eighteen different strains of miniature cattle. [3] Miniature Galloway, Hereford and Holstein have been bred. [2]: 245 [3] In the United States, small zebuine cattle deriving from stock imported from Brazil, the Dominican Republic and Sweden may be registered as "Miniature Zebu"; [2]: 245 in Australia, similar cattle may be known as "Nadudana".
A dilution gene that produces what looks like point coloration, but from a completely different genetic mechanism is the dominant Dun gene, which dilutes the color of the body coat but not the points, including primitive markings—a dorsal stripe down the back and, less often, horizontal striping on the upper legs. On a bay base coat the dun ...
Body color depends on the underlying coat color genetics. A classic "bay dun" is a gray-gold or tan, characterized by a body color ranging from sandy yellow to reddish brown. Duns with a chestnut base may appear a light tan shade, and those with black base coloration are a smoky gray. Manes, tails, primitive markings, and other dark areas are ...
