This page provides an up to the minute summary of data currently available in the database. Parameters reported include minimum and maximum reported genomes sizes (in picograms), mean genomes sizes with standard error (SE), total number of species assayed, and the methods, cell types, and standards used for all available records. Note that the statistics reported here are based on all records in the database -- for maximum reliability, you are encouraged to evaluate the data for your particular group of interest directly. Note also that these C-value summaries do not currently account for instances of polyploidy (though this will be updated in the future).

Because these statistics refer to the database as a whole, they must be cited as follows if used in a publication:

• Gregory, T.R. (2005). Animal Genome Size Database. http://www.genomesize.com.

Please select your group of interest from the list:

• Entire Database (i.e., all animals)
• All Chordates | Amphibians | Birds | Fishes | Mammals | Reptiles
• All Invertebrates | Annelids | Arachnids | Crustaceans | Echinoderms | Flatworms | Insects | Molluscs | Nematodes
• Methods, Cell Types, and Standard Species

(Other invertebrate groups are insufficiently represented for summary stats)
