- Observation Meiosis II kinetochores were diffuse and nearly invisible, sometimes in dark chromatin cups.
- Observation In meiosis I, sister kinetochores protruded from chromosomes and formed distinct fibers.
- Observation No significant internal substructure was detected in the kinetochore proper.
- Mechanism The diffuse kinetochore likely represents the outer domain of a two domain organelle.
- Mechanism The inner domain probably extends into chromatin of the primary constriction.
