This DVD begins by looking at single-gene genetic disorders including recessive disorders such as Tay-Sachs and sickle-cell anemia, dominant disorders such as Huntington's disease, and sex-linked disorders such as hemophilia and color blindness. The program then looks at polygenic inheritance and environmental influences on the expression of genes. Chromosomal inheritance of disorders such as Down syndrome are then explored before looking at the ethical issues involved in genetic testing and the hope promised by the Human Genome Project. 2005.
