Exhibits little change in enzyme activity between late larval and early pupal stages, but there is a substantial increase in late pupal and adult stages. Results in relatively low pupal:adult activity ratio. Aldox-1Pa1/Aldox-1Pa2 has intermediate phenotype.
1.5% recombination with electrophoretic Aldox-1 alleles recorded. The difference between Aldox-1Pa1 and Aldox-1Pa2 is postulated to reside in a cis-acting site that exerts temporal control on gene activity.
