Cellular DNA Content and the Evolution of Teleostean Fishes
Abstract
The haploid DNA content has been determined for 275 species of teleostean fishes. Chromosome numbers are known for 73 of these. DNA content ranges from 4.4 picograms down to a minimum of 0.4. The more specialized or evolutionarily advanced fishes usually have less DNA than the more generalized forms. There are, however, several exceptions which may represent fish groups that are now in the process of evolutionary radiation. Chromosome number and DNA content are correlated, indicating that increases in DNA may have occurred by some form of polyploidy. An increase in DNA, followed by a gradual decrease, which is associated with specialization, appears to have accompanied fish evolution.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
