      Reference

      Testes and ovaries from chbEP3515 or chbEP3515/Df(3L)31A adults are rudimentary. Mutant larval neuroblasts are often arrested in metaphase ot prometaphase, and sometimes show circular mitotic figures and other abnormal anaphases. chbEP3515/Df neuroblasts occasionally show chromatin bridges and abnormal segregation.

      The effects on viability, mitotic phenotype and mitotic progression suggest an allelic series: chbEP3515 < chbv40 < chbEP3403 < chbP4.
