HEREDITY ENVIRONMENT
Is it our DNA or our environment that makes us who we are? Learn about the structures and chemistry of DNA molecules. Students see how genes are passed from parents to off spring and how they determine the traits of an individual. Discover how environmental factors, inside or outside of the womb, can affect a child's health later in life. Viewers also learn about genetic disorders and how counseling and screening can provide health information before or during pregnancy.
