The phrase "fraction of population" is correct and usable in written English.
You can use it to describe a small, precise portion of a group or population. For example, "According to the survey, only a small fraction of the population has access to reliable healthcare."
For genes that are differentially spliced between populations and harbour a sQTL, we evaluated the fraction of population differences in splicing that are attributable to the sQTL, using the mediate function from the mediation R package57.
Once established that a large fraction of population differences in splicing can be attributed to genetic factors, we searched for sQTLs that presented signatures of positive selection, based on levels of population differentiation (FST) and extended haplotype homozygosity (integrated haplotype score (iHS 58,59.
While some Canadian regions have more in common with the low mobility southern parts of the United States than with the rest of Canada, the fact that they represent a much smaller fraction of population is the other reason why overall mobility is lower in the United States.
The last indicator is the fraction of population 14-15 studyingunderg under the old system lower vocational studies.
The budget has been shared between areas using the 120,000 figure as a fraction of population and demography.
We take account of births, deaths and migration with rate of growth (f x,u)), and let (K x, y)) denote the fraction of population that will migrate from position x to y within the time interval ((t, t+ Delta t)).
A more experimentally tractable measure of the effect of migration on survival in challenging environments is the fraction of populations that survive over a given period of time.
Accordingly, we performed growth-dilution-migration experiments with higher antibiotic concentrations (10 μg/ml ampicillin, 16 μg/ml chloramphenicol) and measured the fraction of populations that survived over 10 days.
Rights groups and observers have pointed out that while the number of refugees and migrants heading to Europe has risen sharply in the past year, this migration still only accounts for a tiny fraction of populations.
A larger fraction of populations are differentiated across Cape Mendocino in northern California, and between Oregon and Alaska.
We estimated changes in health outcomes at the county level according to the fraction of population-level grids that fell within county boundaries.
