Finding that several complementation groups are affected may be explained by a microdeletion or by position effect.
Limits of break 1 from polytene analysis (FBrf0034407) Right limit of break 2 from complementation mapping against crn (FBrf0042291) Limits of break 3 from polytene analysis (FBrf0034407)
Heterozygotes are viable and exhibit a pn phenotype. Homozygotes are lethal.
In(1)pn45 carries a small deficiency, as it fails to complement ph-p, ph-d, Pgd and pn.
