Homozygotes show reduced eclosion rates. HemΔ2-6/HemC3-20 animals almost never eclose. A weak disorganisation of the lamina plexus and an abnormal bundling of R-cell axons in the medulla is seen in approximately 70% of homozygous third instar larvae. 20% of the remaining larvae show a stronger disorganisation of the R-cell axons and 10% are indistinguishable from wild type. This axonal phenotype is more pronounced in HemΔ2-6/HemC3-20 larvae.
HemJ1-70/HemΔ2-6 is rescued by Scer\GAL4elav-C155/HemUAS.cHa
