Let's also assume for the sake of simplicity that there is only one gene responsible for eye color and that the allele for brown eyes (B) is dominant over the allele for blue eyes (b). Let's also assume that blue-eyed people and brown-eyed people randomly intermarry.1. What would be the ratio of brown-eyed to blue-eyed people in the world?
