Gene Sequencing (01:56)
The sequencing of the human genome has allowed the identification of 25,000 genes. Four percent of these genes "make all the difference." Currently the sequencing of an individual's genome is prohibitively expensive. Soon, this will change. Many diseases can now be traced to their genetic origins.
Genetic Roots of Anorexia (02:24)
Meet a mother and daughter, each of whom has anorexia. Each talks about her disorder and the genetic nature of the disease.
Eating Disorders and Genetics (02:36)
How do biology and genetics influence eating disorders? It appears that people who suffer from eating disorders are "wired differently biologically." Anorexia is a complex disorder caused by multiple genes as well as multiple environmental factors.

Human Genome: Mental Disorders (02:42)
Psychiatrist Patrick Sullivan explains how science is able to find specific gene bases on the 3,000 km long human genome. Sullivan studies genes that are associated with three mental disorders: bipolar disorder, autism, schizophrenia. Other studies focus on genetics and addiction to hard drugs.
Genetics and Longevity (01:51)
Gerontologist Thomas Perls studies of longevity and genetics. What are the secrets of centenarians?
Genetics and Fidelity (02:17)
Anthropologist Helen Fisher explains that there is a genetic basis for one's propensity to be a faithful partner. Science is "getting to the bottom of pair-bonding behavior." What role does Freud's work in psychoanalysis play in light of these scientific discoveries?
Sperm Donor Baby (05:02)
Personality is partially engraved in the genes. A 22-year-old opera singer, Leandra is the product of what was called the Nobel Prize sperm bank. Journalist David Plotz explains the sperm bank designed to create baby geniuses. Leandra's mother explains her choice to be impregnated by a sperm donor.

Sperm Bank Industry and Customization of Baby Characteristics (02:30)
Sperm banks are an industry today. See a promotional video for a sperm bank. Couples can literally customize the characteristics of the child by shopping for specific sperm donors.
Choosing Embryos (03:01)
Pre-fertilization diagnosis is a process of creating a number of fertilized eggs that can be analyzed for affected genes. Only unaffected embryos will be implanted in the mother's womb.
