At long last, a new edition of this highly-regarded, classic veterinary reference. Since 1984, discoveries in molecular genetics and cell biology have significantly transformed our understanding of animal development. With the imminent release of the canine genome, followed shortly by genomes for other domestic species, the opportunities for discovering the basis for species and breed differences - anatomically, developmentally and in patterns of disease susceptibility - are unprecedented. This new edition is an up-to-date, highly illustrated, four-colour text, providing veterinary students and researchers with accounts of important developmental features of domestic species, accompanied by integrated cell, molecular and anatomical discussions of the etiology of congenital defects.
