Frequency classes assume that ancestral and derived states are inferred at variable nucleotide sites (unfolded distributions). The original tests suggested by Sawyer *et al*. (1987), McDonald and Kreitman (1991), and Templeton (1996) were performed on folded distributions. Monte Carlo tests of homogeneity were employed in lieu of *G*-tests, Fisher's exact tests, and χ^{2} tests employed in the references.
