Synonymous substitution per synonymous site (K s) vs. nonsynonymous substitution per nonsynonymous site (K a) for 16 human–New World monkey coding sequence pairs. The values calculated for RNase k6 pairs are indicated with black circles. The shaded circles represent values calculated for 13 coding sequence pairs originally reported by Rosenberg et al. (1995)including ECP, EDN, interleukin-3, CD59, protamine P2, protamine P1, SRY, insulin a-chain, interferon-γ; complement C4a, insulin b-chain, c-myc proto-oncongene, and EGF-like growth factor. (See Rosenberg et al. 1995 for Genbank accession nos. for these sequence pairs).
