Bipolar and monopolar kinetochore orientation at anaphase I in meiosis of 2R(2D)xR hybrids. a kinetochores linked by microtubules b bi–polar kinetochore orientation c thin kinetochore MT bundle – like interpolar MT bundle. Immunostaining was undertaken with anti–α–tubulin (green) and anti– CENH3 (red) antibodies, DNA staining with DAPI (blue). Scale bar: 10 μm.
