chromosomes

Explores the foundations of human biology: structure, genetics, and diseases.

A book for high school students about the history and developments made in the area of cloning.

This book will help kids understand why animals' offspring look like their parents, as well as why they may share traits with their parents and other family members. The science behind heredity is explained in simple, age-appropriate text, while graphic organizers help to show how genes and heredity work.

This book uses simple language and detailed images and charts to explain how genetic ancestry testing is done, what it can, and cannot, reveal about a family tree, and the potential unintended consequences of being tested.

A book about depictions of human cloning in science fiction as well as the ethics and possibility of human cloning in the real world.

Bloodstains provide clues as to how a crime had been committed. When a speck of blood falls on a surface, it leaves a shape and stain. This is called bloodstain evidence. Each individual carries DNA that is unique to him or her, except for identical twins.

As scientists continue to make genetic breakthroughs, society inches ever closer to confronting the stuff horror movies are made of. Cloning a mourned pet is simply strange, but the thought of human cloning is terrifying. Manipulating genes to reduce genetic disease is encouraging only until we consider the ethical implications of potentially creating a master race. Genetically engineering crops and animals can address many problems like disease, climate change, and world hunger, but altering the environment could have catastrophic results for Earth. Articles presenting these issues from persuasive points of view help readers understanding the controversies surrounding genetic engineering today.

Gene therapy is a perennial hot-button issue in today's news cycle. This relatively new and experimental field involves inserting genetically altered genes into cells to replace defective genes. It can treat genetic disorders or provide a specialized disease-fighting function. The multifaceted topics surrounding gene therapy DNA, techniques, challenges, and risks are presented in this clear, understandable text, so that readers can grasp the ramifications and ethical concerns of this incredible technology. While gene therapy is currently only being tested for the treatment of diseases that have no cures, genetic engineering for many ailments and conditions is a very real possibility of the near future.

Examines the causes and effects of genetic disorders such as Down Syndrome, hemophilia, sickle-cell anemia, and others; discusses genetic screening and research efforts in gene therapy; and includes names of suggested sources of additional information.

Explores the X chromosome in human life, history, and culture, including the role it plays in gender, disease, and, possibly, sexuality; and discusses its evolutionary future.
