This textbook helps you to prepare for your next exams and practical courses by combining theory with virtual lab simulations. The “Labster Virtual Lab Experiments� series gives you a unique opportunity to apply your newly acquired knowledge in a learning game that simulates exciting laboratory experiments. Try out different techniques and work with machines that you otherwise wouldn’t have access to. In this book, you’ll learn the fundamental concepts of the genetics  of human diseases focusing on: Monogenic Disorders - Cytogenetics - Medical Genetics - Viral Gene Therapy In each chapter, you’ll be introduced to one virtual lab simulation and a true-to-life challenge. Following a theory section, you’ll be able to play the relevant simulation that includes quiz questions to reinforce your understanding of the covered topics. 3D animations will show you molecular processes not otherwise visible to the human eye. If you have purchased a printed copy of this book, you get free access to five simulations for the duration of six months. If you’re using the e-book version, you can sign up and buy access to the simulations at www.labster.com/springer. If you like this book, try out other topics in this series, including “Basic Biology�, “Basic Genetics�, and “Basic Biochemistry�. Please note that the simulations included in the book are not virtual reality (VR) but 2D virtual experiments.
