The dopamine receptor D5 gene shows signs of independent erosion in toothed and baleen whales [PDF]
To compare gene loci considering a phylogenetic framework is a promising approach to uncover the genetic basis of human diseases. Imbalance of dopaminergic systems is suspected to underlie some emerging neurological disorders. The physiological functions
