Elevated Evolutionary Rates among Functionally Diverged Reproductive Genes across Deep Vertebrate Lineages

Table 1

Functional classification of reproductive (testis, ovary, gonadal) and non-reproductive orthologs in vertebrate species. Genes were assigned to at least one of seven functional categories (see Section 2.2 for explanation). Non-reproductive genes are found in neither the testis nor ovary EST libraries but are present in other tissues.
