Table 2. Correlation Coefficients and Partial Correlation Coefficients for the Three Factors Gene Class (Duplicate or Singleton), CAI (in D. melanogaster), and K S (of Representative Pairs).
Significance was tested for the direct and partial correlation coefficients using the statistics and , respectively, where n is the sample size, m is the number of variables held constant, and r is the rank correlation coefficient (Sokal and Rohlf 1995)
aFor this parameter, representative pairs were given a value of either 0 (for a singleton) or 1 (for a duplicate)
