Homozygotes show misorientation of the mitotic spindle in dividing neuroblasts in the larval brain.
Animals homozygous for the "PL26" chromosome show pupal lethality and this lethality is uncovered by Df(3R)p712. However, PL26PL26/Df(3R)p712 animals do not show the spindle misalignment phenotype associated with PL26PL26.
