Answer: Recessive Gene. Homo zygote Allele.
Explanation:
Each gene is composed of two alleles. Alleles can be Dominant or Recessive. A Dominant gene is always expressed on the Phenotype (XX/Xx); A Recessive gene expresses on the Phenotype if both alleles are the same (xx).
In this statement, it's implied that the gene that codes for "blue-eyes" is recessive, since both parents had to provide the same allele for it to express.
