      (Giansanti et al., 2004)

      spermatid & nucleus | supernumerary

      (Giansanti et al., 2004)
      Detailed Description
      Statement
      Reference

      Over half of ferZ5477 spermatids have over four nuclei with one large nebenkern, which may result from defects in the mitotic divisions preceding mitosis. A large proportion of ferZ5477 mutant spermatids have exactly four nuclei, indicating a cytokinetic failure in both meiotic divisions. A smaller proportion (<4%) have two nuclei and a large nebenkern, indicating failure of only one of the meiotic divisions.
