CommentsIncomplete fission-zone formation with arrest in late-cytokinesis, with the new oral apparatus often abnormal and frequently wedged within the arrested furrow (39°). Fairly high lethality in crosses. Clear-cut temperature-sensitive expression: no expression at 28°, penetrance high but not 100% at 39° C.
