Excerpt from Studies of Heredity in Rabbits, Rats, and Mice In some Wild mammals the white-spotting is more extensive, taking the form of a definite pattern, as in skunks, the harp-seal, and the Malay tapir. The color pattern of skunks, while characteristic, is known to vary slightly, the value Of a pelt increasing with the amount of black which it contains, a fact which the incipient industry of skunk-farming in the United States notes with interest. Selective breeding is being directed toward the establishment of all-black strains and no doubt it will ultimately be successful.

Excerpt from Genetic Studies of Rabbits and Rats But in a majority of cases variation due to genetic causes occurs in association with that due to non-genetic or environmental causes; in fact, it is possible to distinguish between the two only by the results of systematic selection. When the environment is kept constant and a race does not change in response to selection, we assume that no genetic variation is present. But if the race does change in response to selection, we have no alternative but to assume that the variation is genetic in character. Body-size in birds and mammals shows well the simultaneous yet distinct action of genetic and non-genetic agencies. The amount and quality of the food supplied to an animal limits its size, yet if food is supplied in abun dance and of proper quality, some races of animals attain greater size than others. This is the result of genetic differences. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

A concise guide to the care of small mammals, Ferrets, Rabbits, and Rodents: Clinical Medicine and Surgery covers the conditions seen most often in veterinary practice. The book emphasizes preventive medicine along with topics including disease management, ophthalmology, dentistry, and zoonosis. More than 400 illustrations demonstrate key concepts related to radiographic interpretation, relevant anatomy, and diagnostic, surgical, and therapeutic techniques. Now in full color, this edition adds coverage of more surgical procedures and expands coverage of zoonotic disease. From editors Katherine Quesenberry and James W. Carpenter, along with a team of expert contributors, the "Pink Book" provides an authoritative, single source of information that is hard to find elsewhere. A logical organization makes it quick and easy to find important information, with each section devoted to a single animal and chapters within each section organized by body system. Over 400 photographs and illustrations highlight key concepts such as radiographic interpretation and the main points of diagnostic, surgical, and therapeutic techniques. A chapter on ophthalmology provides hard-to-find information on eye care for ferrets, rabbits, rodents, and other small mammals. Coverage of preventive medicine includes basic biology, husbandry, and routine care of the healthy animal. The drug formulary supplies dosage instructions for ferrets, rabbits, guinea pigs, chinchillas, hamsters, rats/mice, prairie dogs, hedgehogs, and sugar gliders. Chapter outlines offer at-a-glance overviews of the contents of each chapter. Handy tables and charts make it easy to find key information. Expanded Zoonotic Diseases chapter adds more depth along with the latest information on the rising potential for disease transmission to humans as exotic pets become more popular. Additional surgical procedures for each species are included, some with step-by-step instructions accompanied by color photographs and line drawings. Full-color images show the sometimes minute structures of these small animals and make accurate diagnoses easier, especially for lymphoproliferative diseases of rabbits, endoscopy, cytology, and hematology.
