An interchromosomal duplication is a segment of one chromosome inserted into another chromosome. This page shows interchromosomal duplications for chromosome 2 isolated by classical mutagenesis with breakpoints characterized primarily by polytene cytology.
An introduction to interchromosomal duplications gives a general overview of duplication screens. The Origin column below references this overview. Some duplications have more complicated origins and structures than suggested by the figures in the Introduction and columns below, so please look into the detailed history of any duplication important to your work.
