Taken as a whole, the results obtained in this work will be helpful to study how individuals of genus Odontesthes deals with environmental salinity changes, as well as in studies of population structure and demographic history in this species and related taxa.
Both algorithms had some success with identification of individuals to genus with 63 93% of query sequences correctly identified depending on the marker used (Figure 2).
The fossil, a shell fragment from a large individual of the genus Doedicurus, yielded enough genetic material to completely reconstruct DNA from the creature's mitochondria, the tiny energy factories found in each living cell.
Individuals of one genus or species do resemble each other, however, and this resemblance is the foundation of universal concepts in the human mind.
However, these fossils cannot be assigned to P. robustus with certainty because individuals of the genus Homo are also found in those layers (e.g., Trinkaus and Long 1990).
Stalks of adult individuals of the genus Haliclystus also present fibrillar components at the attachment sites [33].
Since only few individuals of each genus were selected to test the performance of our EST-SSRs, the levels of polymorphism detected in this study cannot be considered a general attribute of EST-SSRs.
Ever since Müller's [ 23] observation that the operculum forms at the tip of a pinnulate radiolus in individuals of the genus Serpula, the tentacles have been considered homologous to the operculum.
We have sequenced 33 individuals of this genus from British Columbia, with some collections from the north at times looking very much like this species in field-identification, but which nonetheless are genetically assignable to A. fastigiata and not A. plicata.
Despite this variability, 5S rDNA is frequently more stable in its position than 35S rDNA, which may vary substantially in distribution between related species (e.g., in Aloe[ 45]) and even between cells in individuals of species of genus Allium[ 46].
An individual of the related genus Cinygmula was used as an outgroup.
