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.  

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
