"The few 'unique' features that potentially define the new species need further scrutiny, as they may represent individual variation, or variation at the population level," he said.
Most include too few images to show taxonomic variation or variation in characters and character states.
Moreover, we gave priority to the gene's coding region and did not adress regulatory variation, or variation in the remaining noncoding regions.
Importantly, increasing the read depth n ji only reduces the sampling error, but does nothing to reduce experimental variation or variation due to sequence context.
If, on the other hand, the purpose is to describe (fine-scale) spatial variation, or variation as function of environmental or population differences, samples of the appropriate spatial scale or relevant environments or populations should be sequenced.
Our results are based on a snapshot measurement; we have only one blood sample from each woman and can infer nothing about intra-individual variation or variation over time.
Although there are some studies on individual variation in gibbon songs [ 9, 11], there is no systematic study available to confirm whether individual variation or variation at group level is high enough to contradict a possible relation between song structure and genetic relatedness among closely related species.
Epigenetic inheritance occurs when environmentally-induced and developmentally-regulated variations, or variations that are the result of developmental noise, are transmitted to subsequent generations of cells or organisms (Jablonka & Lamb 2005).
For example, we have not looked at inversions and copy number variations or variations in gene expression leading to phenotypic changes or complex polygenic traits.
Variation in voltage fluctuation or variation in speed between high-speed shaft and low-speed shaft varies the rotation of wind turbines.
