Genes and the traits they produce are passed down because in general they have or had an evolutionary purpose. Sometimes just knowing that a problem you have is inbuilt and part of a genetic package can be helpful in the way you deal with it. This volume is a useful guide for anyone who wants to learn more about how genes affect them and their family's everyday lives. Structured around the human life cycle - starting with babies and ending with death - this title addresses issues such as the determination of personality and physical characteristics, the likelihood of disease, sex and risk-taking. In conjunction with research into family history and awareness of personal strengths and weaknesses, this book can help readers to maximize their environment and avoid problems.
