Why Are Your Eyes That Color? is a new video from Brain Stuff. The video isn’t an explanation of genetic traits (that is mentioned briefly) as it is an explanation of what actually gives your eyes a particular pigment.

The following TED-Ed lesson provides a good complement to the Brain Stuff video above. In How Mendel’s Pea Plants Helped Us Understand Genetics, students receive a crash course in heredity, genotypes, and punnett squares through the story of Mendel and his study of peas. The video is embedded below. The full lesson with questions is available here.
