Comment:

G to A nucleotide change at the second or third position of the Trp codon leads to a nonsense mutation (exact site of mutation unspecified).

Comment:

      Strong dorsalization: loss of ventral epidermis.

      (Isoda et al., 1992)

      Embryos derived from homozygous females are incompletely dorsalised at 29oC; a tube of dorsal cuticle is formed. These embryos usually form some Filzkorper material and a small piece of head skeleton. At 18oC, the embryos are much less dorsalised and form ventral setae.
