WebHemophilia A Hemophilia A is the most common severe inherited coagulation disorder in animals and human beings. In dogs, as in other species, the disease arises as the result of spontaneous mutation. Once hemophilia appears in a family, the defect can then be transmitted through many generations. Large-scale genetic screens can identify the genes or mutations that affect the phenotype of an organism. Analyzing the phenotypes of mutant genes can also aid in determining gene function. Most genetic screens have used microorganisms, in which genes can be easily deleted. For instance, nearly all genes have been deleted in E. coli and many other bacteria, but also in several eukaryotic model organisms such as baker's yeast and fission yeast. Among other discoveries, su…
