Advances in Genetics increases its focus on modern human genetics and its relation to medicine with the merger of this long-standing serial with Molecular Genetic Medicine. This merger affirms the Academic Press commitment to publish important reviews of the broadest interest to geneticists and their colleagues in affiliated disciplines.

• Genetics, the science of heredity, lies at the heart of biology, and many diseases are impacted by an individuals genetic make-up. The field of genetics is rapidly evolving and new medical break-throughs are occurring as a result of advances in knowledge of genetics. Advances in Genetics continually publishes important reviews of the broadest interest to geneticists and their colleagues in affiliated disciplines
• This volume of Advances in Genetics contains the following articles: Targeted Expression of Tetanus Toxin; Germ-line Transformants Spreading Out to Many Insect Species; Genes Mediating Sex-Specific Behaviors in Drosophila; and Evolutionary Analyses of Genes and Their Functional Implications.
