In Drosophila (fruit flies), the wild type eye color, brick red, is actually produced by the deposition of two pigments in the eyes, a dull brown pigment and a brilliant red pigment. These two pigments are produced by the action of two different, non-allelic (and non-linked) genes. Each of these genes has two alleles, a dominant one which causes normal the production of the pigment controlled by the gene, and a recessive one which is defective, and causes none of that pigment to be produced. Thus, a normal eye- color fruit fly must have at least one dominant allele for each of these genes. If a fly is homozygous for the defective, recessive allele of the gene which produces the brown pigment, that fly will have only the brilliant red pigment in its eyes. This condition is called "cinnabar." For this reason, the gene responsible for producing the brown pigment is called the "cinnabar" gene (genes are often named for the effect their mutant alleles have on the phenotype). The symbol for this gene is a two-letter symbol, cn. The dominant allele is Cn and the recessive allele is cn. Careful with this symbol. Never separate the c's from the n's. So a cinnabar-eyed fly would have the genotype cn cn.
