Why do I have brown eyes?
The genes we inherit from our parents determine things like our height, looks, hair color and eye color. This passing of characteristics from parent to child is called heredity. If your mother has brown eyes, and your father has blue eyes, there’s a good chance you’ll have brown eyes. That’s because the brown-eye gene is dominant, and the blue-eye gene is recessive. The dominant gene usually prevails over the recessive one. It’s possible, however, for you to have blue eyes if both your parents have brown eyes. They probably inherited recessive blue-eye genes from their parents and passed them on to you.
i think if ur father has a strong x then u have blue eyes n if ur mother has a strong y then u have brown eyes
