a Values given in parentheses are partial correlations, factoring out effects of coding fraction and recombination rate, respectively

b Direct correlations between coding density and TE abundance are calculated by making bins that exclude TE contributions to DNA length. Partial correlations, factoring out recombination rate effects, use the original bins for accurate estimation of recombination rates over real physical distance. Two-tailed significance
