Based on this information, what is Cupcake's phenotype for the eye color trait?

 - brown eyes
 - red eyes
Cupcake's genotype for the eye color gene is EE. Cupcake's genotype of EE has only E allelles. The E allele is for brown eyes. So, Cupcake's phenotype for the eye color trait must be brown eyes.
To check this answer, consider whether Cupcake's alleles are dominant or recessive. The allele for brown eyes (E) is dominant over the allele for red eyes (e). This means E is a dominant allele, and e is a recessive allele.
Cupcake's genotype of EE has two dominant alleles. An organism with at least one dominant allele for a gene will have the dominant allele's version of the trait. So, Cupcake's phenotype for the eye color trait must be brown eyes.
