Have you ever wondered why we look the way we do? It's all because of genetics! Let's imagine a family. Mom has brown eyes and Dad has blue ones. They have two kids, both with brown eyes! Why is this? Brown eyes are 'dominant' and blue eyes are 'recessive'. This means the brown eye gene overpowers the blue eye gene. That's why the kids have brown eyes.
