Addressing the inter-individual variation in response to
The impressive variation amongst biological individuals generates many complexities in addressing the simple-sounding question what is a biological individual? A distinction between evolutionary and physiological individuals is useful in thinking about biological individuals, as is attention to the kinds of groups, such as superorganisms and species, that have sometimes been thought of as Genetic variation occurs mainly through DNA mutation, gene flow (movement of genes from one population to another) and sexual reproduction. Since environments are unstable, populations that are genetically variable will be able to adapt to changing situations better than those that do not contain genetic variations. SUMMARY Functional genomics research using Fundulus heteroclitus has focused on variation among individuals because of the evolutionary importance and value of Fundulus in explaining the human condition (why individual humans are different and are affected differently by stress, disease and drugs). biological variation and the analytical variation. The intra-individual biological variations were calculated by means of the following formula (5,14): (CV I) 2 =(Total CV)2 - (Analytical CV)2 One-half of the mean CV I is proposed as the quality specification for imprecision, i.e., CV A < 0.5 CV I. The inter-individual variance (SD G 2 Human variability, or human variation, is the range of possible values for any characteristic, physical or mental, of human beings.
a species are identical. The differences between the individuals in a species is called variation. What are cells 16 Jul 2014 Quantifying BiologicalQuantifying Biological VariationVariation σ2 Analytical= σ2 Individual= σ2 Group = Average variance of replicate Mutation, meiosis and sexual reproduction causes variation between individuals in a species. Natural selection requires variation among members of a species We have argued that variation is as fundamental to the biological nature of human beings as any single gene sequence can be. To study this aspect of the How variation can be introduced into a species. in fact even in our population what leads to one person having you know dirty blonde hair one of one of the most fundamental things about biology and it's so fundamental that a l Most features of an individual phenotype are polygenic and show continuous variation.

Statistical Methods: With Special Reference to Biological Variation
Major causes of variation include mutations, gene flow, and sexual reproduction. DNA mutation causes genetic variation by altering the genes of individuals in a population. Gene flow leads to genetic variation as new individuals with different gene combinations migrate into a population.

Many analytes of interest in the clinical laboratory can vary over an individual's lifetime, simply because of natural biological factors involved in the aging process. Differences in measurable biological values, characteristics, or traits, within one individual under different conditions for the individual such as fasting, season of

Different results are usually observed when a quantity is measured in different specimens from the same individual obtained over a time span. For an individual, this variation is due to the imprecision of the measurement procedure, that is to say the metrological variability, as well as Se hela listan på acutecaretesting.org Biological Variation.

Biological variation is divided into intra(within)-(CV I) and inter(between)-(CV G) individual variation (5). The former is characterized by rhythmic aberrations of multiple frequencies (6) and the latter is caused by different set-points around which each individual varies (7).
