Correlation matrix heatmap of all samples using Pearson’s Correlation coefficient of methylation values. All samples show very slightly higher correlation with samples of the same genotype (~ 0.96), than with samples of a different genotype(~ 0.955), reflecting possible genotype-specific methylation patterns but still showing variation between clones within each genotype. F. mandshurica methylomes show low correlation with all F. excelsior methylomes (~ 0.94). The low coverage F. excelsior samples, particularly F.exc 35–5, F. exc 40–1, and to some extent F.exc 33–5, also show lower correlation with other F. excelsior trees (~ 0.95)
