Lethal at 25oC over all non-conditional Ddc alleles tested (n=42) and all non-conditional, non-leaky l(2)37Ca alleles tested (n=27).
Specific DDC activity of newly eclosed adult CyO/Ddc heterozygotes, as percentage of CyO/+ control: 57.8 chromosome also lethal over l(2)37Ca
Mutation is not a deficiency.
May be double mutant at the l(2)37Ca gene or alternatively be a polar mutation which alters or eliminates Ddc+ and l(2)37Ca+ functions. Certain combinations of Ddc alleles show intragenic complementation.
