Available in PDF, EPUB and Kindle. Book excerpt: Although the physical nature of the gene was essentially clear by the late 1950s, the study of gene action, particularly during the development of higher organisms, is ongoing. Wallace and Falkinham explain how intimately progress has relied on technology. Initially limited to an examination of external features and subsequently to classical genetics and cytogenetic analyses, research was revolutionized by Watson and Crick's discovery of the double helix structure of DNA.
