Genetics helps explain a lot of things, like what makes you unique, why you look like other members of your family, and why some diseases run in your family. Human genetics is more an applied science than a fundamental science. One benefit of studying human genetic variation is the discovery and description of the genetic contribution to many human diseases. Inheritance is the process by which genetic information is passed on from parent to child. Inheritance can occur via two different overall mechanisms—genetic inheritance or epigenetic inheritance. This book deals with emerging technologies and clinical applications in inheritance biology.
