01Narrative

Clarkia biloba is a species of flowering plant in the evening primrose family known by the common name twolobe clarkia and two lobed clarkia.CalFlora Database: Clarkia biloba (two lobed clarkia) . accessed 3.23.2013 Clarkia biloba is endemic to California, where it is known from the Sierra Nevada foothills; one subspecies can also be found in the San Francisco Bay Area. It grows in chaparral, oak woodlands, and yellow pine forest habitats. As the putative progenitor species of Clarkia lingulata it is often used in examples of evolution outside the usual model of allopatric speciation. As such this plant is one of the best plant examples when considering "quantum speciation," a concept closely aligned with peripatric speciation, parapatric speciation and sympatric speciation.

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 Clarkia biloba has left across the world's sequence archives.

06Genome at a glanceCCDB · GoaT

The complete instruction manual Clarkia biloba 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.

Genome sizehow big the whole instruction manual is

Genome size978 000 000 bp

Measured in base pairs (bp) — the individual letters of DNA (human ≈ 3.2 Gb, a bacterium a few million). The chart places this genome on a logarithmic scale — each step to the right is ten times bigger — among reference organisms. Across species a bigger genome loosely tracks with larger cells, slower growth and lower-energy lifestyles (powered flight favours small genomes) — yet it does not imply more genes or a more advanced organism (the long-standing C-value paradox).

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.
