For a given pair of species the numbers in each cell below the diagonal represent, from top to bottom: the number of KOGs in which the average number of detected domains from the CDD collection (cut-off E = 10^-3) in the proteins from the species to the left is greater than that for the species to the right; the number of KOGs with equal average number of domains; the number of KOGs in which the average number of domains is greater for the species to the right (for example, D. melanogaster has a greater number of detected domains than H. sapiens in 470 KOGs, the same number in 3,214 KOGs, and a smaller number in 805 KOGs). The numbers above the diagonal are the statistical significance of the difference, P(χ²).
