  • a Twenty hybrid-lethal regions and 3 hybrid-semilethal regions (*).

  • b Breakpoints defining physical location of hybrid lethal are from combined information of multiple deficiencies (see Table 1).

  • c Viability, ratio of Df:Bal hybrid males for region (mean of multiple overlapping lethal deficiencies).

  • d Y, lethality confirmed by >1 overlapping deficiency (see Table 1); N, not confirmed.

  • e E, embryonic lethality; PE, postembryonic lethality.

  • f See Table 3 results.

  • g See Table 2 results.

  • h Hybrid lethality of region 021C02-03; 021C08-D1 was detected with Df(2L)al and then confirmed using a newly extracted Df(2L)al deficiency chromosome (see materials and methods).
