To generate embryos lacking different portions of the X heterochromatin, two types of stocks were used: (1) males carrying a deficient X chromosome missing part of the heterochromatin (generally fog-) and a duplication on the Y chromosome that complements the deficiency, and (2) males carrying a duplication of X on the Y chromosome which covers part of the X heterochromatin were crossed to attached X females. In both cases males were crossed to attached X females. In the first case, one quarter of embryos lack most of the X chromosome except the duplication of X on Y. These embryos were identified according to their defects during cellularization. Another quarter of the embryos carry the deficient X chromosome as their sole X chromosome. These embryos were identified according to their defects in posterior midgut formation during early gastrulation. In the second case, one quarter of embryos that lack most of the X chromosome except the duplication of X on Y were identified according to their defects in cellularization or posterior midgut formation. !Name=168: Xhet mapping !Exptid=114340 !Name=175:Xhet mapping !Exptid=114342 !Name=114n: Xhet mapping !Exptid=114345 !Name=114f: Xhet mapping !Exptid=114348 !Name=186n: Xhet mapping !Exptid=114350 !Name=186f: Xhet mapping !Exptid=114353 !Name=B2580 !Exptid=113685 !Name=B5280 !Exptid=114129
