The study of genetics is certain to come to the forefront and demand our immediate attention in the 21st century, for modern geneticists now assert that ""all disease has a genetic link."" The Kidds (Mother Nature's Pharmacy, p. 896, etc.) thoroughly examine the evolution of the study of genetics, from its first pioneer in the 1880s, George Mendel, to the current and complex Human Genome Project of the 1990s. The identification of malfunctioning genes, gene-replacement therapy, the use of genetics in crime detection, biohazards, cloning and its ethical considerations--all of these are carefully analyzed in this resource. Socially significant and timely, this latest book in the Science and Society series elucidates the concerns, controversies, and promises that genetic research holds for our ever-changing society. Intriguing, unsolved genetic mysteries conclude this inclusive text to spark the imagination and spirit of inquiry in the young mind.
