While it is great that there are so many resources dedicated to genetics and comparative genomics, it is somewhat odd that relatively little attention has been paid to comparative phenomics. I mean, every researcher who has tried to make a transgenic animal knows that a genetic mutation or variation means nothing if there is no phenotype associated with it. So, enter PhenomicDB, a website looking to remedy the negligence. PhenomicDB is a genotype/phenotype database for seven different species, with an additional eighth grab-bag category labeled “other,” that compiles the data from various single-species databases into one place. The database can be searched by a number of parameters, and the results can be restricted to only genotypes or phenotypes. The website has a clean design and is simple to use (and hey, the logo is really cool!).
