Obtaining a true measure of species diversity is difficult, as the strains selected for whole-genome sequencing are generally chosen to examine a particular phenotypic trait, subjecting any resultant measures of diversity to selection bias.
The diversity of that selection – a vast modern art museum, an office block for a venerable imperial financial institution, an electronics factory in an industrially depressed area – contrasts somewhat with today's record of City skyscraper, luxury flats, luxury flats, luxury flats.
One approach for deriving meaningful information on population genetics is by comparing multiple nucleotide sequences, including arbitrary regions [ 19], and subsequent assessment of calculated patterns of diversity, tests of selection (Tajima's D, Fu and Li's F* and D* statistics), gene flow, linkage disequilibrium and migration [ 20].
An evaluation of growth rates, energetics and nutritional indicators in fish differentially selected for vulnerability to angling may provide further insight into the diversity of traits under selection as well as the consequences of selection from a fisheries management perspective.
Although the retrospective might draw more patrons at another date, its scope — 51 features and 30 shorts, with possible additions to come — speaks to Mr. Jones's ambitions for the festival, as does the genre, narrative and tonal diversity of all the selections.
Also there must be a relatively relaxed bottleneck in domestication permitting a high level of diversity in neutral genes before the loss of diversity by selection can be detected.
Genomes that have experienced selective pressure due to their functional role in phenotypic diversity contain unique patterns of genetic diversity called signatures of selection (Oleksyk et al. 2010).
Given the diversity of solutions, the selection of the most appropriate systems for an application has become a challenging task.
To illustrate diversity of FGs a selection of some more exotic functionalities is shown in Fig. 4.
The size and diversity of the post-selection thymocyte population is regulated by the ligands made available in the thymus by antigen processing and presentation.
As has been established in a diversity of taxa, natural selection can favor some codons for an amino acid over the others.
