... Genes are given a full name, like speck, and a symbol, like sp. In general, gene symbols are capitalized if the original allele was dominant. Thus, gene names are case-sensitive, so b and B denote different genes (black body color and Bar eye, respectively). Alleles are indicated by superscript, exc ...
