Population maps of special gene sets: Genes of highest expression (top 10%) preferentially accumulate in a few metagenes in spots A – F (spots are assigned in agreement with Figure 10 ) whereas the consistently absent genes (~3-5% of all genes) are found in the area of minimum variability (see variability map in [6]). Housekeeping genes selected as consistently present in all tissues (not-absent, ~15% of all genes) and as the top 10% most stable expressed genes are compared with the set of housekeeping genes taken from ref. [31]. The gene sets enriched in selected highly populated spots (h1 – h11) are given in Table 2. The Venn diagrams show the overlap between different gene sets as illustrated.
