01Narrative
Polygala curtissii, the Curtiss' milkwort or Appalachian milkwort, is a species of flowering plant in the milkwort family. It is native to the Southeastern United States, where it is found primarily in the southern Appalachian Mountains and the Piedmont. Its natural habitat is open, sandy meadows, and woodlands. It is an annual that produces pink-purple flowers in the summer.

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 Polygala curtissii has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualPolygala curtissii 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.
