Cytotype coexistence in the field cannot be explained by inter-cytotype hybridization alone: linking experiments and computer simulations in the sexual species Pilosella echioides (Asteraceae)

Table 3 Two stable states in the Simple Model and the field-observed proportions of individual cytotypes

Ploidy level	2x	3x	4x	5x	6x	7x
Stable state I	0.9872	0.0092	0.0035	5.39E-05	1.88E-06	9.18E-08
Stable state II	0.0000	0.0000	0.9093	0.0000	0.0907	0.0000
Field-observed proportions	0.06	0.73	0.2	0.01	0	0

System of monocarpic plants with no clonal growth. Numbers in the first two lines in table are equilibrium proportions (after 500 iterations) of individual ploidy levels. If the system is initialized by diploids and tetraploids only, stable state I is reached when initial proportion of diploids is greater than 0.497, stable state II when initial proportion of diploids is smaller than 0.497
