  1. Seven features were computed for adjacent gene pairs in S. cerevisiae (met, metabolic network distance; cex, gene co-expression; igd, intergenic distance; let, density of lethals; rec, recombination rate; cre, gene co-regulation; pro, protein-protein interaction network distance; see Materials and methods). The table shows the mean value of each of these properties for adjacent gene pairs that remained (-co) or did not remain (-nc) as adjacent in the corresponding comparator yeasts. Species ordered according to phylogenetic distance to S. cerevisiae, the closest being C. glabrata. Note that there does not exist yet a consensus phylogeny, for example [22,18]. The last two rows list the proportion of adjacent S. cerevisiae pairs retained as adjacent in the corresponding comparator and total number of homologues pairs (both orthologues might not be in the same chromosome). A smaller number was obtained (9% and 1,850 homologue gene pairs, respectively) when using C. albicans as comparator species [17]. *Yeasts that diverged after the whole genome duplication event.
