    Enhancer additivity and non-additivity are determined by enhancer strength in the Drosophila embryo

    Jacques P Bothma et al.
    Quantitative live imaging assays reveal that multiple enhancers often fail to work in an additive fashion in the patterning of the Drosophila embryo, and sometimes even interfere with one another.
