      Statement
      Reference

      Adult flies carrying tsgtwi.PM appear normal and show normal viability. The normal bilateral symmetry of mitotic domains 1, 5 and 6 is restored in homozygous tsg2 embryos carrying tsgtwi.PM. The number of amnioserosa cells is normal in embryos carrying 4 copies of tsgtwi.PM. Does not alter the number of amnioserosa cells produced in embryos carrying two copies of dppSal20, in heterozygous dppH48 embryos or homozygous dpphr4 embryos.
