To note: all three are blond, ellie's eyes are brown, her brothers are blue.
Ellie's father is homozygous for eye colour but her mother is heterozygous. She passed a 'blue eye' gene to the boys and a 'brown eye' gene to Ellie. Brown hair is dominant over blond but ellie and her brothers are all blond.
By reading that what could the answer to this question be. I would like some help not the answer thanks.
