• Hexaploid forms with 42 chromosomes are also known, but rare.
• Like the closely related yellowfish, it is hexaploid.
• It is presumably hexaploid like the other yellowfish.
• There are no wild hexaploid wheats, although feral forms of common wheat are sometimes found.
• This species is also unusual in its genus in including diploid, tetraploid and hexaploid races.
• As far as can be told, all " Labeobarbus " species are hexaploid.
• This grass often reproduces by apomixis, producing seeds without diploid, tetraploid, or hexaploid.
• The y-type genes at the Glu-A1 locus are not expressed in hexaploid wheat.
• Earlier research conducted by CIMMYT made use of a chemical hybridising agent to evaluate heterosis in hexaploid triticale hybrids.
• The species has been found in a polyploid series with diploid, tetraploid, hexaploid, octoploid and dodecaploid individuals.
• Haploid cells are produced from pollen or dihaploids ( and the doubled dihaploids are, respectively, tetraploid or hexaploid ).
