Organism Nematode Caenorhabditis elegans
Reference Stein LD et al., The genome sequence of Caenorhabditis briggsae: a platform for comparative genomics. PLoS Biol. 2003 Nov1(2):E45 DOI: 10.1371/journal.pbio.0000045 p.183 right column 3rd paragraph & p.189 right column 2nd paragraphPubMed ID14624247
Comments "The C. elegans genome now totals 100,273,501 bases (WS103 release- June 2003) and consists of six contiguous segments of DNA corresponding to the C. elegans chromosomes." These are autosomal chromosomes I,II,III,IV,V and chromosome X. Notice that this is the n value, i.e. counting the sister chromosomes as one chromosome. Counting the sister chromosomes as two separate chromosomes the 2n=12 value is obtained.
