Table 3. The upper part of the table (grey cells) contains Dice coefficients (reflecting the epigenetic similarity among the rye taxons); the lower part (blue cells) contains the U-values (showing the differences between the rye taxons); both sets of data were calculated on the basis of MSL and NML loci polymorphism.
