Fig. 2: Samples cluster by cold treatment and sex.

A MDS plot of male (triangle) and female (circle) expression when kept at 19°C (empty shapes) or 6°C for 5 days (filled shapes). Distances between samples in the MDS plot approximate the log2 fold change of the 500 genes with the largest biological variation between the libraries. B Heatmaps and hierarchical clustering of gene expression (log2 CPM). Values on each node show the bootstrap support from 1000 replicates.
