Long ears are dominant (E) in rabbits. If one parent is homozygous dominant for the long ear trait and the other homozygous recessive, what is the only possible genotype of the offspring?

Ee

Two dark brown rabbits have four offspring. Three of the offspring are dark and one is white. What does this tell you about the parents' genes for fur color?
Dark brown is dominant and white fur is recessive. Both parents are heterozygous.
