Comparison of the number of genera per order for all orders.
One way this "value" or "interest" is assessed is by examining the diversity that exists above the species level, in the genera, families, orders, classes, and phyla to which species belong (see taxonomy).
Finally, these three ortholog databases represent a potential of 329 different markers (out of a 376) available among 62 fungal species (35 genera, 18 orders) (Figure S2).
Numbers of assignments to selected genera and orders were normalized to an equal sample size.
The final filtered data set is composed of 413 sequences with 25 species, 21 genera, 14 orders, 9 classes, and 6 phyla.
Bacteria are classified into species, which are organized into higher taxonomic ranks such as genera, families, orders, etc., based on levels of similarity among them.
Additionally, we also report the performances on the original data set (1964 bacterial genomes, 1157 species, 590 genera, 120 orders, 57 classes, and 36 phyla).
A typical data set might include a list of hundreds of bacterial species that are hierarchically organized into different groups, including genera, families, orders, classes and phyla.
The number of Mhc genes can differ greatly between and within species, and may show no sequence orthology between genera or orders – e.g. class I gene number and organization differences between human and chimpanzees (reviewed in [ 10]).
Across mammals, molecular phylogenies have helped identify convergent morphological changes associated with foraging ecology at multiple hierarchical levels from genera to orders (Hunter & Jernvall, 1995; Delsuc et al., 2001; Reiss, 2001; Ruedi & Mayer, 2001).
