Exploring stochastic and spontaneous methylome variation across transgenerational lineages. A, Heat maps of average methylation across 100-bp tile-based DMRs identified from pairwise comparisons, with one-dimensional hierarchical clustering of rows, between all samples. B, Heat maps representing two-dimensional hierarchical clustering of correlations (Pearson’s r) of genome-wide DNA methylation, in all sequence contexts, averaged across 100-bp tiles for all G0 and G5 progeny.
