Duplication appears wild type when homozygous or when hetero- zygous with ast. Heterozygous with S, it has normal or only slightly roughened eyes. Various combinations of S and ast alleles have been introduced into the duplication. Through unequal crossing over, a triplication and a quintuplication of the region [i.e. Dp(2;2;2)S and Dp(2;2;2;2;2)S] have been synthesized. # Dp(2;2)S56f cytology: Dp(2;2)21C6-D1;22A3-B1. origin: Associated with In(2LR)Px4. references: CP627.
