Declining transition/transversion ratios through time reveal limitations to the accuracy of nucleotide substitution models.

abstract：BACKGROUND:In most species, males compete to gain both matings (via pre-copulatory competition) and fertilizations (via post-copulatory competition) to maximize their reproductive success. However, the quantity of resources devoted to sexual traits is finite, and so males are predicted to balance their investment betwe...
