In this episode of the popular series, students will have a chance to learn about genes, and how human traits are passed from generation to generation. Such physical characteristics as hair color, skin color, and whether hair is curly or straight are all dependent upon genetic background. The Science Guy compares genes to a blueprint, not for a building, but for a kid. Using some flashy graphics and other devices to help students retain the information, Bill Nye shows how human cells follow this blueprint to create a human being. ~ Alice Day, Rovi
