The latter are typically easier to distinguish from the majority of the population by appearance, name, and language ability.
We might expect natural selection to favor individual moths in this new population whose appearance better matches the background, as they will avoid predation.
An Association for Industrial Archaeology publication describes Greater Manchester as "one of the classic areas of industrial and urban growth in Britain, the result of a combination of forces that came together in the 18th and 19th centuries: a phenomenal rise in population, the appearance of the specialist industrial town, a transport revolution, and weak local lordship".
Whenever occasional staining was present on cells in the mERlow population, its appearance was similar to that seen on mERhigh cells (data not shown).
In the Coventry validation population ill appearance was defined as a modified Yale score of more than 6. 27 We included all candidate predictor variables in the model independent of their statistical contribution.
In a genetically uniform crop pathogen population the appearance of a novel virulent pathotype capable of overcoming the deployed resistance may easily lead to a selective sweep culminating in the presence of a single clone or clonal lineage (this is particularly the case in asexual foliar pathogen populations).
All existing studies of inbred populations show that incest increases the rate of appearance of negative recessive genes.
While an extra tooth may have eventually developed from this extra blood supply, its frequency among the general horse population makes its appearance in the Exmoor pony unremarkable.
Dexamethasone improved the growth, the maximum number of cell population doublings, and appearance of control and FSHD myoblasts, as did regular additions of basic fibroblast growth factor.
While the MDA-MB-436 cells display a typical epithelial morphology, the most conspicuous feature of the 436.1 population was the appearance of giant cells with abundant cytoplasm, often exhibiting multiple nuclei or a multilobular nucleus (Fig. 2).
