Human genome research will be one of the dominant themes of science in the 1990s. To assist its progress, new technologies and concepts are expected to emerge from the analysis of other organisms' genes and chromosomes. Comparative data on the genetic organization of different species, therefore, have particular importance. Since 1980, Genetic Maps has been the only comprehensive source of such information. This new, sixth edition is published in two formats: as a series of six paperback volumes, each containing a variety of genetic maps from one group of organisms, and as a cloth-bound, reading-room edition containing the complete collection of maps from all 129 species listed. Book 1 - Viruses Book 2 - Bacteria, Algae, and Protozoa Book 3 - Lower Eukaryotes Book 4 - Nonhuman Vertebrates Book 5 - The Human Maps Book 6 - Plants
