The 5' (distal) end of this breakpoint corresponds to 2L:1 ,586,840 and the 3' (proximal) end corresponds to 2L:1 ,586,845 (release 6 coordinates), meaning that 4bp of genomic sequence is deleted at this breakpoint.
The 5' (proximal) end of this breakpoint corresponds to 2R:24 ,117,046 and the 3' (distal) end corresponds to 2R:24 ,117,059 (release 6 coordinates), meaning that 12bp of genomic sequence is deleted at this breakpoint.
This chromosome enhances PEV.
The pericentric inversion, In(2LR)22A3-B1;60B-C, enhances balancing power of In(2L)Cy + In(2R)Cy since it causes the single crossover between the two Cy inversions to yield complementary products that are dominant lethal. Heterozygote shows interchromosomal effect; used to increase crossing-over and gene conversion in ry region (Chovnick, Ballantine and Holm, 1971, Genetics 69: 179-209); also causes non-disjunction of compound autosomes (Lindsley and Grell, 1969).
