Results of GLMs evaluating the effect of genotype, sex and temperature on principal coordinate analysis (PCA) scores. PCA scores derived from variation in methylation epigenotypes between samples (R and DAN males and hermaphrodites incubated at high and low temperatures), based on the presence/absence scores of 63 polymorphic MS-AFLP markers. Significant values shown in bold. Genotype represents the scores of the first principal component of the MspI PCA analysis.
