Many of the fundamental concepts in genetics are applicable across various organisms-microorganisms, plants, animals, and humans. This book presents a concise discussion of these universal genetic principles. In addition, this book also puts a spotlight on an aspect of genetics that is distinctly human, that of genetic disorders. Many of these are rare, have no cure, and have no specified cause. This book discusses representative genetic disorders as well as some of the DNA-based technologies that enable a better understanding of these disorders
