What is a small piece of DNA that tells a cell how to express a trait?
EleanorJohnsongp7905
DNA uses chromosomes 23 from your mom, and 23 from your dad. (46 together). If both your parents have brown eyes, there's a big chance of getting brown eyes.If both your parents have brown eyes and you get blue eyes that is a ressesive trait.
