Genetic Variation

  • John H. Andrews
Part of the Brock/Springer Series in Contemporary Bioscience book series (BROCK/SPRINGER)


Because variation (among entities at any level) provides the raw material on which evolution acts, this chapter sets the stage for later comparisons in the book by reviewing briefly the generation and maintenance of genetic variation in different kinds of organisms. While some sections of the text are controversial, for the most part the chapter is more factual and less speculative than those which follow.
