Other claims from this paper (9)
- Observation All Aloinae species except three were diploid (2n=14), with four long and three short chromosomes in the basic number.
- Observation Gasteria maculata was tetraploid (2n=28).
- Observation Haworthia reinwardtii and H. tesselata were hexaploid (2n=42).
- Observation Aloe had the longest chromosomes.
- Observation Haworthia had the shortest chromosomes.
- Observation Gasteria and Haworthia had two pairs of long chromosomes with satellites (2L1+2L4).
- Observation Aloe had various combinations of SAT-chromosomes.
- Mechanism The karyotypes were explained by karyotype alteration such as elimination and translocation of satellite and subsequent hybridization.
- Observation The analysis of Aloinae karyotypes supported Heitz's hypothesis of SAT-chromosomes.
