• Sommario/riassunto: Authored by a very eminent geneticist, this text gives students a thorough appreciation of the development and potential of analytical genetic techniques. Beginning with a consideration of both the classical Mendelian and the molecular biological aspects of genetic analysis, the book goes on to discuss progress in three key areas of genetics. Firstly the elucidation of the detailed structure and overall organization of the genome, secondly the way that genetic differences at the molecular level account for heritable variation in populations, and finally an explanation of how the genes control
