Values of α and ωa in csd-Allelic Regions and Underlying Nucleotide Divergence and Nucleotide Diversity.
| d0 | d4 | π0 | π4 | α | ωa | |
|---|---|---|---|---|---|---|
| PSD and exon 8 | 0.084 | 0.007 | 0.054 | 0.067 | 0.93 | 11.19 |
| PSD | 0.081 | 0.011 | 0.065 | 0.105 | 0.92 | 6.74 |
| Exon 8 | 0.088 | 0 | 0.039 | 0.023 | 1 | n.c. |
Note.—The proportion of amino acid substitutions driven by positive selection (α) and the rate of nonsynonymous substitutions relative to the rate of synonymous substitutions (ωa) were calculated using nucleotide divergence (to two csd alleles of A. cerana) and nucleotide diversity (within 87 csd alleles of A. mellifera) on 0- and 4-fold degenerated sites. n.c.: not calculable.
