      Statement
      Reference

      Dual phenotype of elevated DDC activity and increased resistance to dietary and methyl dopa relative to Oregon-R derived controls (DdcC). Specific DDC activity of newly eclosed adults 141% and DDC crossreacting material (CRM) 137% of the DdcC control. Interpretation of phenotype identical to that for DdcRE. Specific DDC activity of newly eclosed adult CyO/Ddc heterozygotes, as percentage of CyO/+ control: 141
