Construct: Mutant hb NRE, included within a DdeI-XbaI 152 nucleotide fragment with all six conserved guanosines mutated to uracils, is fused 3' to the 10kb genomic BamHI fragment of hbC20-hb.
lethal - all die during embryonic stage | dominant | maternal effect
some die during embryonic stage | dominant | maternal effect | maternal effect
abdominal segment | maternal effect
All abdominal segmentation is repressed in affected embryos. The phenotype is indistinguishable from the mutant nos phenotype.
