      Malpighian tubules arrest early in their morphogenesis in homozygous embryos. The tubules are typically spherical at stages 16 and 17 (when they are elongated in wild-type embryos) and have more cells than recently evaginated tubules. Some embryos have tubules that are at least partially tube shaped and slightly elongated. The tip cells are present.
