Df(2L)HisC, His4rΔ double homozygotes rescued by 12x copies of the HisGU gene unit (bearing His1HisGU.wt, His2AHisGU.wt, His2BHisGU.wt, His3HisGU.wt and His4HisGU.wt) are semi-lethal and adults are fertile and show normal lifespan.

Epidermal Df(2L)HisC clones in His4rΔ homozygotes that also express variants of the HisGU gene unit (12 copies; bearing His1HisGU.wt, His2AHisGU.wt, His2BHisGU.wt and His3HisGU.wt with either His4HisGU.wt, His4HisGU.H4K16R, His4HisGU.H4K16Q or His4HisGU.H4K16A) are able to form normal-looking adult structures with sensory bristles.
