Replacement (R) and synonymous (S) polymorphisms within A. thaliana and fixed differences between A. thaliana and A. lyrata are indicated for each domain.

  • * significant at the P < 0.05 level

  • ** significant at the P < 0.01 level.

  • a Analysis for the entire protein (“all”) is equivalent to the McDonald-Kreitman test.

  • b Core and noncore domains are defined in Reichmann et al. (1996).

  • c Probability values for the contingency tables are calculated using Fisher's exact text.
