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

 - red eyes
 - brown eyes
Hoppy's genotype for the eye color gene is EE. Hoppy's genotype of EE has only E allelles. The E allele is for brown eyes. So, Hoppy's phenotype for the eye color trait must be brown eyes.
To check this answer, consider whether Hoppy's alleles are dominant or recessive. The allele for red eyes (e) is recessive to the allele for brown eyes (E). This means E is a dominant allele, and e is a recessive allele.
Hoppy'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, Hoppy's phenotype for the eye color trait must be brown eyes.
