A catalogue of chromosome counts for Phylum Nematoda.

Nematodes are important biological models in genetics and genomics, with research driven by basic biological as well as applied questions. The presence of holocentric chromosomes, clades with frequent polyploidy and the phenomenon of programmed DNA elimination make nematode karyotypic diversity of particular interest. Here we present a catalogue of published karyotypes of nematode species, rationalising and normalising descriptions from the previous 135 years.
