The diversity of animal genetic resources includes diversity at species, breed and within-breed level. Known are currently 8,800 different breeds of birds and mammals within 38 species used for food and agriculture. [1] The main animal species used for food and agriculture production are cattle, sheep, goats, chickens and pigs. In the livestock ...
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 ...

Pigment color differs from structural color in that it is the same for all viewing angles, whereas structural color is the result of selective reflection or iridescence, usually because of multilayer structures. For example, butterfly wings typically contain structural color, although many butterflies have cells that contain pigment as well. [3]
Expected progeny differences (EPD) are an evaluation of an animal’s genetic worth as a parent. They are based on animal models which combine all information known about an individual and its relatives to create a genetic profile of the animal’s merits. These profiles are then compared to other individuals of the same breed.
The D locus dilutes black pigment to a blue-grey color usually called Blue. It is a recessive trait like Liver. When a dog has both Liver and Blue dilution, it will appear to be a light, warm-gray color known as Isabella. This is the color of Weimaraners. This color also has alternate names such as Liliac or Silver.
In 2007 one genetics lab began offering a test for what they believed was a marker for seal brown, and later for an agouti allele which they believed caused the brown color. [27] [28] However, the underlying research was never published and the test was suspended by 2015 due to unreliable results. [29] [30]
