a KS: synonymous substitutions per synonymous site and standard deviation calculated using a modification of the method described by Li (1993) implemented in the “diverge” program in the GCG software package (Wisconsin Package Version 10.3, Accelrys)
b Other gene pairs in stratum 2 in Mus musculus have KS ranging from 0.739 to 0.758. Other gene pairs in stratum 3 in Mus musculus have KS ranging from 0.467 to 0.579 (Table 1). The smaller fragments of both Smcx/y and Zfx/y have lower KS values than their full-length counterparts
c Smcx/y KS calculated from 657 bases
d Zfx/y-2 KS calculated from 996 bases
