This is a non-science majors human genetics text that clearly explains what genes are, how they function, how they interact with the environment, and how our understanding of genetics has changed since completion of the human genome project. It is a clear, modern and exciting book for citizens who will be responsible for evaluating new medical options, new foods, and new technologies in the age of genomics. - Over fifty new pieces of colour-coded art present basic concepts of single-gene inheritance, chromosome structure, and DNA structure and function, helping students visualize the material they have just read. - Up-to-date genome information has been integrated throughout the text, giving students a modern perspective of human genetics. - Because the study of human behaviour has greatly expanded, Chapter 7 from the fourth edition (Multifactorial and Behavioral Traits) has been divided into two separate chapters in the fifth edition: Multifactorial Traits (covering basic methods and concepts) and The Genetics of Behavior (covering specific behaviours).
