‘Although trisomic plants segregate for only two genetic conditions, euploidy and hyperploidy, the system is simpler to use than B-A translocations.’
‘To obtain a more precise determination of genome size in some of these lines, multiple individuals from a few of the lines with genome content values furthest from euploidy were grown and their genome size was determined.’
