Gene

This is a picture of an eye, featuring its blue coloration. Eye color is an example of a phenotype, or physical characteristic, determined by genes. A gene is a unit of heredity that is passed from parent to offspring. It is a specific locus, or location, on a strand of DNA, in which the nucleotide sequencing encodes a functional RNA or protein product. Protein synthesis is what determines physical characteristics. Most biological traits are influenced by polygenes, or many different genes.
