All genetically characterized insertions are shown, including those that were not included in established stocks because they were subsequently lost or were not kept because they were inserted on the TMS or CyO balancers. Also included are variegating insertions selected as Cy flies, which were omitted from Figure 1 (see its legend); most of these were new insertions in the CyO chromosome, which were discarded, but some were demonstrated to be on other chromosomes during subsequent outcrosses and thus were included in the established stocks.

• a Established stocks do not include variegating insertions on the CyO and TMS balancer chromosomes or any that were lost or sterile. Although new insertions on CyO were kept, we have not included them in the totals because they are likely to be less useful in future analysis.

• b Insertions are linked with either the X or the X^Y chromosomes.
