Other claims from this paper (8)
- Observation Each Allium species has seven V-shaped chromosomes.
- Observation A. roylei has the longest genome, 63.44 µ.
- Observation A. cepa type has the shortest genome, 56.18 µ.
- Observation Allium cepa and A. pskemense have the same genome length.
- Observation The subterminal chromosome of Allium carries a satellite attached to its short arm.
- Observation Allium chromosomes have no other conspicuous morphological markers such as knobs or heterochromatic blocks.
- Observation Chromosomal differences among A. cepa, A. cepa type and A. galanthum are less pronounced than among A. pskemense, A. roylei and A. drobovii.
- Mechanism Chromosomal differences among these Allium species are attributed to inversions, translocations and pairing in unequal chromosomes.
