01Narrative
Athyrium americanum, the alpine lady fern, is a species of fern in the family Aspleniaceae. It is native to the Russian Far East, subarctic North America, and the west to west-central United States. It occurs at higher altitudes and latitudes than Athyrium filix-femina, the common lady fern.
No narrative description available for this taxon yet.

05DNA & barcodingmolecular
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 Athyrium americanum has left across the world's sequence archives.

06Genome at a glanceGoaT
The complete instruction manualAthyrium americanum 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.
