Table 1.

Concordant and discordant phyletic patterns between DR, TT, Aquifex aeolicus (AA) and Thermotoga maritima (TM)

AA+TM+ AA-TM-
DR-TT+ 47 (21.7) 110 (135.3)
DR+TT- 23 (48.3) 326 (300.7)

Note: Expected number of COGs under the assumption of independence is shown in parentheses. Probability, associated with the χ2 test, is 2 × 10-12 for the complete 2 × 2 table and 3 × 10-6 for the 2 × 1 table (concordant vs. discordant).
