One population, characterized by relatively small individuals with a maximum length of 6.6 metres (21.7 feet) and significant tooth wear, preys on fish, seals, and other animals.
In contrast, the other population, characterized by larger individuals that can grow to a length of 8.5 metres (27.9 feet) and possess relatively little tooth wear, is thought to feed solely on whales and other dolphins.
A sole instance of the artificial evolutionary process starts from a population characterized by a particular distribution of notochord stiffness and ends (in Long's experiments, at the tenth generation) with a population characterized by a different distribution of stiffness.
Neural crest cells (NCC) are a transient, embryonic cell population characterized by unusual migratory ability and developmental plasticity.
Data came from a nationwide inpatient database in Japan, showing no benefit of PMX-HP in a less severe population characterized by a low mortality rate.
Myeloid-derived suppressor cells (MDSCs), a heterogeneous population characterized by their ability to suppress T-cell responses, may play a major role.
Within this cell subset, blockade of Notch signaling ablated a distinct population characterized by high expression of the adhesion molecule ESAM, which is expressed on endothelium and regulates neutrophil extravasation.
The KS statistics determines if the samples of both rings are drawn from the same continuous population characterized by the cumulative distributions F(x i ) and F(x j ).
This method is especially well-suited in Iceland due to its founder population characterized by long haplotypes (a set of SNPs that tend to be inherited together), and the availability of extensive genealogy information of its inhabitants in the large pedigree database "Íslendingabók".
We sought to fill several important gaps in the literature by comparing the course and symptom profiles of major mood disorders between Anabaptists, a unique population characterized by varying degrees of cultural and genetic isolation, and cases drawn from the general population who were matched on age, gender, and diagnosis.
A convenient way to quantify the number of shared gametes is by means of the proportion μ P of shared gametes between populations characterized by distributions P and Q, with respect to the total number of gametes in the population characterized by P. We emphasize that μ P is not only a property of population P, but of the pair of populations being compared.
