Look at all those eyes staring at you, and notice how human eyes come in different colors. Some eyes are blue with specks of green. Others are brown with a gold ring. In very rare cases, a person's eyes might even look red. Eye color is a trait that can vary from person to person. However, all humans are almost exactly the same biologically. Think about all the things you have in common with the other students in your class. You all have a digestive system and a beating heart. You all use your lungs to breathe in and blood vessels that carry oxygen to all parts of your body. You all have a brain that processes the information coming from each of your sensory receptors. In fact, you have almost exactly the same set of instructions written in your DNA. So, how do humans have all these things in common, but have very different colored eyes? In this lesson, you will learn how the DNA found inside of a cell holds the key for how to make a complex organism, like a human. First, you will learn that many of our traits are determined by the different proteins found inside the body. You will learn that the amount and structure of a protein are important in determining slight differences in a trait, like different eye colors. Also, the instructions for making these proteins are found in a person's DNA. Finally, you will learn that DNA is inherited from parents in the form of chromosomes. Throughout this lesson, you will notice the trend that something's structure helps to determine its function. Introduction p

Studying genetics gives us the ability to know how traits (like glowing in the dark) form, how they have changed over time, and how we can change them now to help people. These pigs are glowing because a gene from a glowing jellyfish was added to the DNA of a pig while it was an embryo. As the embryo grew, it made lots of new cells that had the jellyfish gene inside of them. With this gene, the pig cells make a protein that makes the pig glow.

What do DNA, genes and chromosomes do? These materials help make proteins for the body. You can think of them as similar to items used to make food in a kitchen. Analogy:

As a Parks and Wildlife Official, you have received a call from a concerned tourist who thinks that glowing toxic sludge is polluting the beaches. You explain that he has just witnessed plankton bioluminescence. He asks you to explain, and you tell him that some living things can make their own light with chemical reactions in their cells. This ability to make light is called bioluminescence. What doo you think the ability to make light is? The ability to make light is a trait.
