Bill Nye the Science Guy (1993)

Episode Overview

The traits that define your appearance, such as eye color, nose shape, and hair texture, are determined by your genes. These are not the denim garments, but rather the intricate strands of chemicals found within your cells. Genes serve as a detailed blueprint for your body, guiding your cells in their development. All living organisms possess genes, which are inherited from parents—half from the mother and half from the father. This genetic inheritance continues through generations, as genes from a mother's egg and a father's sperm combine to create a unique plan for a new life. Consequently, baby humans, puppies, and plants resemble their parents due to these inherited genes.
