Left limit of break 1 from polytene analysis (FBrf0034407) Right limit of break 1 from inclusion of csw (FBrf0042629) Left limit of break 2 from inclusion of pcx (FBrf0042629) Right limit of break 2 from polytene analysis (FBrf0034407)
Mutation changes the level of w expression in ph-plac+3 flies; eye colour is darker.
Df(1)278.4B1/Df(1)pn38 heterozygotes are viable and display a pcx phenotype: sterile, produce inviable embryos exhibit a strong neurogenic phenotype.
Heterozygotes are viable and exhibit a pn phenotype. Homozygotes are lethal.
