01Narrative
Glyceria acutiflora, the creeping mannagrass, is a perennial grass found in the north-eastern United States and in north-eastern Asia. Its specific epithet acutiflora means "acute-flowered". It has a diploid number of 40.
No narrative description available for this taxon yet.
A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Glyceria acutiflora has left across the world's sequence archives.

The complete instruction manualGlyceria acutiflora carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.
Chromosomes & ploidyhow the DNA is packaged
2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants.
