Doubts and questions regarding breeding carriers have been present among dog breeders since first development of modern dog breeds. With the fast development in the field of genetics and molecular biology, a number of DNA tests became available for purebred dogs. These tests became a powerful tool in the control of the quality of one’s dog, but DNA tests also enabled planning of breeding program on a whole new level.
Cats from all over the world display a great variety in expressions of cat coat colour and for this reason were always a subject of research in fields of genetics and inheritance. Influence of certain genes on the cat’s coat colour can be relatively easy to explain, while some of them may be more complicated than expected.
The bond between humans and dogs is unique, closer than between any other species. This bond is a result of dog breeding, which started to form more than 100 000 years ago with the first domesticated wolf.
After the first domestication of dogs from the grey wolf, the number of the dog population grew quickly, matching the rising number of agrarian societies. Even in those early ages of the first dog populations, people were breeding dogs in order to acquire desired traits. One of the most important traits was, and still is, the dog coat color.
Feline infectious peritonitis (FIP) is a relatively new cat disease, recognized as clinically significant in late 1950s. Despite the fact that it is one of the most researched infections in cats it continues to be a major killer of young cats.
Cat blood group The AB cat blood group system is both unique and typical of blood groups of other species. It is unique because it appears to be the sole major blood group system. Since it has only two common alleles and the vast majority of cats have the same blood type A, the cat…
