Genetic nomenclature for Drosophila melanogaster

Edited by Chang Zhu
1. The gene name begins with a lowercase letter when the gene is named for mutant phenotype recessive to the wild-type in a normal diploid. The name begins with an uppercase letter when the gene is named for a mutant phenotype that is dominant.

2. Wild-type is used for the wild-type allele.

3. The character / is reserved as a homologue separator in genotypes.

4. Alleles of a gene are designated by superscripts or a hyphen, e.g., whiteapricot or white-apricot.

5. Gene, allele, aberration and transponson/transgene-construct names and symbols are italicized in printed text. When used to indicate phenotype, rather than genotype, then the name or symbol is printed in non-italic type.
