Correlation of pN/pS with genomic factors

Variable	Effect	P‐value
GC3	−0.2372	<2.2 × 10–16
Expression	−0.3689	<2.2 × 10–16
Protein size	0.0227	0.0056
Density of protein coding sites	0.0067	0.4127
Recombination rate (cM/Mb)	−0.0309	1.85 × 10–04
Population recombination rate (2.Ne.r)	−0.0394	1.52 × 10–06

Dispensable chromosome	0.2590	0.0162

Effects and P‐values are calculated using Kendall's correlation of ranks. GC3, GC‐content at third codon positions; TEs, transposable elements.
