The third edition of this award-winning text provides new and updated knowledge about genetics issues relevant to nursing practice. Read in sequence or used as a reference, this is a comprehensive overview of how genetics affects the care that nurses provide. In addition to a summary of basic human genetics and discussion of the Human Genome Project, this new edition includes the latest research findings and implications about inheritance, major genetic disorders (cytogenetics or chromosomal, inherited biochemical, and congenital anomalies), and genetics in twin studies. A consideration of the ethical impact of genetics on society and future generations, as well as information on assisted reproduction round out the overview. It includes over 100 illustrations and photos of specific genetic disorders; tables and figures on the distribution of disease; and an extensive appendix listing associations, organizations, and websites relevant to genetics.
