Other claims from this paper (12)
- Observation C. dentata was diploid with 2n=18.
- Observation C. Banksii was diploid with 2n=18.
- Observation C. mexicana was aneuploid with 2n=60.
- Observation One bivalent was nucleolus attached at diplotene and diakinesis in diploids.
- Observation Two bivalents were nucleolus attached at zygotene and diakinesis in C. mexicana.
- Observation Interstitial chiasmata persisted in 35% of diploid cases at diplotene but terminalised at metaphase.
- Observation Multivalents were rare in diploids.
- Observation Aneuploid chromosome associations ranged from trivalents to groups of eight.
- Observation Rings and chains of four and six chromosomes were found.
- Observation Secondary association in diploids had a maximum grouping of 3 (2)+1 (3).
- Observation The authors inferred derivation of the diploid number from basic number 4, indicating allopolyploidy.
- Observation Chromatin bridges at Anaphase I indicated inverted segments in diploids.
