Table 2.

Methylation levels are more consistent across species than across organs.

	Hypomethylated CpG (<20%)			Hypermethylated CpG > 80%
Organ	Liver	Brain	p-value	Liver	Brain	p-value
Mouse	62.7%	61.1%	0.5	24.35%	24.2%	0.5805
Zebrafish	24.1%	14.78%	0.03	63.4%	68.9%	0.2692
p-value	2.35e - 09	2.32e - 14		2.35e - 09	2.34e - 11

Ratios are the percent of methylated CpGs out of all the CpG₁₀ detected. The p-value on the right is between liver and brain in mouse and zebrafish. The p-value on the bottom is between mouse and zebrafish in liver and brain.
