TL;DR: This study demonstrates that phenotypic expressivity of the scallopedE3 (sdE3) mutation of Drosophila melanogaster is background dependent and is the result of at least one major modifier segregating between two standard lab wild-type strains and demonstrates that the epistatic interaction between sdE3 and an optomotor blind mutation is backgrounddependent.
