      Very little ventral cell invagination is seen by mid to late germ band extension.

      (Hemavathy et al., 1997)

      Ventral furrow fails to form.

      (Ashburner et al., 1990)

      sna2/Tp(2;1)Scorv23 adult escapers are occasionally produced, which often have missing halteres or show a hemithorax phenotype. Homozygous embryos fail to form a ventral furrow. Cephalic furrow formation, invagination of the endoderm and germ band elongation do take place in these embryos. Embryos show varying defects in the segmental denticle belts.

      (Grau et al., 1984)
