To some persons ""genetics"" is just fruitflies in bottles, or Mendel counting poas. If you, too, number yourself among the deprived souls to whom DNA is nothing but a meaningless abbreviation, read this up-to-date survey of the ""new genetics."" It's lively and interesting and is written by the famous American geneticist George Beadle and his wife Muriel. The average teenager or research scientist will be familiar with most of the material, but adults over 30 years of age will learn much about human evolution, Mendelian laws, biochemistry, cell structure, DNA, etc. Technical jargon is kept at a minimum. Since developments in this science are revolutionizing practices in fields as diverse as medicine and atomic power it will pay the taxpayer to understand what his money is going for. Compares favorably with Ruth Moore's The Coil of Life and Scheinfeld's famous Your Heredity and Environment.
