01Narrative

Fritziana ohausi is a species of frog in the family Hemiphractidae. It is endemic to the mountains of coastal southeastern Brazil in Rio de Janeiro, Espírito Santo, and São Paulo states. The specific name ohausi honors Friedrich Ohaus, a German physicist and herpetologist. Common name Petropolis treefrog has been proposed for this species.

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 Fritziana ohausi has left across the world's sequence archives.

06Genome at a glanceGoaT

The complete instruction manual Fritziana ohausi 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.
