Mia wishes her blue hair was inherited so that she wouldn't have to dye it, but Sam explains that eye color is. The video does not expound upon the concept of alleles. It does, however, describe inherited traits vs. learned behavior, and dominant vs. recessive genes. All in all, this would be a fitting introduction to your heredity unit. Note that you may want to add the terms dominant and recessive to the key vocabulary. A fun reinforcement would be to take a class survey of students' and their parents' eye colors.
