DNA methylation landscape of Yesso scallops with different shell colours. A Density plot of 5-methylvytosine in ^mCG, ^mCHG and ^mCHH sequence contexts. The first circle (outermost) represents the 30 longest scaffolds in the genome of the Yesso scallop; circles 2–5 represent the ratios of each sequence context (i.e., ^mC/covered C, ^mCG/covered CG, ^mCHG/covered CHG, ^mCHH/covered CHH); circles 6–9 represent the average methylation levels of each sequence context. B The proportion of ^mC in the three sequence contexts
