Can brown eyes and hazel make a blue eyed baby?

No, brown eyes and hazel eyes cannot produce a blue-eyed baby. Eye colour is determined by the amount and type of melanin in the iris. Brown eyes have a high concentration of melanin, hazel eyes have a medium concentration, and blue eyes have a low concentration. In order to produce a blue-eyed baby, both parents must have at least one copy of the blue eye gene. Since brown and hazel eyes are dominant traits, they will mask the blue eye gene if present. Therefore, it is impossible for two parents with brown or hazel eyes to produce a blue-eyed baby.
