Carlson received a blue-eyed allele from both of his biological parents. what is the term to describe this gene pattern

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.  

is this a psat question, if so do not cheat try your best.
