Accounts are appearing on some facet of genetics in nearly every issue of scientific magazines and often in the daily newspapers. This book sets out to cover the fundamentals of the subject without the details in a much larger genetics text in order to provide background reading for those not studying the subject. It features humans (a lot), other mammals (a good deal) and occasionally other animals to illustrate principles. Supported with numerous figures and short vignettes, it will be useful to a wide audience from chemists, pharmacists and healthcare professionals.
