But scientists believe fluctuating asymmetry, in which individuals in a population possess a variety of differences in brain shape, may result when environmental factors affect the brain's development.
The second paradoxical result is that when both types of movement are present in the same population, persistence results are often worse than those for a population possessing just one of the two processes, even if the 'total movement scale' (the sum of larval dispersal distance and adult home-range size) is the same (Figures 8).
In this study conducted among the Singapore Chinese, a population possessing a high risk for HCC but a very low prevalence of alcohol consumption, we have provided the strongest epidemiologic evidence to date that smoking is a causal factor for HCC development.
In the selection-centric logic, amino acid or protein sequence varies according to nucleotide variation but sometimes is selected by external forces when the number of individuals in a population, possessing either advantageous or disadvantageous mutations, changes toward either maxima or minima.
I test the hypotheses using an agent-based model in which individuals in a single population possess an ecologically-important trait that is encoded by a Boolean network of varying topologies, and sizes ranging from 16 to 256 genes.
Compared with other known carcinogens, a model prostate epithelial NSC population possesses a remarkable survival selection advantage toward arsenic over their differentiated isogenic counterparts (Tokar EJ, Waalkes MP, unpublished data), which would afford perpetuation but continued targeting during arsenic insult.
Hence, the wide scale identification and functional characterisation of single genetic elements that result in hypervirulence would greatly enhance our understanding of the costs and benefits that could arise when individuals within a pathogen population possess the ability to cause a greater disease load.
Eighty per cent of the British population possesses a passport, versus America's thirty-five.
The student population possesses a powerful combination of dynamism, youth and brain power – perfect for turning a business idea into a reality.
This secondary invasion event is supported both by historical records [35] and by the genetic data presented here, which indicate that the Dokai Bay population possesses a subset of the nuclear allelic diversity present in the source population at Tokyo Bay (Table 5).
