Variation in ITS2 copy numbers within Symbiodinium cells. A non-linear relationship existed between the proportion of ITS2 copies of type C100 (CC100:CTOTAL) and the total number of ITS2 copies within the cell (CTOTAL). Homogeneous C100 cells hosted significantly more ITS2 copies than the genetically heterogeneous cells, or those featuring a homogeneous C109 array (second order polynomial regression, p = 0.027).
