M^aa and F^aa = number of amino acids in male and female respectively.

pD = p-Distances at the amino acidic level.

Ks and Ka = divergence of protein genes in synonymous (Ks) and non synonymous (Ka) sites respectively.

SE = Standard Error.

Ka/Ks = ratio values between Ka and Ks.

*: comparisons between Mcox2 and Mcox2b genes.
