Extended Data Fig. 2

Plots show variation explained by the first three principal components of PCAs carried out separately on samples from Fujairah (top row) and Abu Dhabi samples (bottom row). Samples from adults (squares) and sperm (circles) tend to pair by colony identity. Samples from reciprocal larval crosses E7 x S8 and E8 x S7 (red triangles) are positioned midway between S7 and S8 along all plotted axes, suggesting equal contribution from both parents to their DNA methylation patterns. The sole egg sample, E8, is located close to S8 and A8, indicating that the transmission of epigenetic patterns from parent to either gamete type is unbiased.
