As of May 2019, EFLM is managing the new biological variation database. We were honored to host this database for 15 years. Desirable Specifications for Total Error, Imprecision, and Bias, derived from intra- and inter-individual biologic variation

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.

Biological variation has generally been defined as random fluctuation around the homeostatic set point for each individual (within-subject or intra-individual biological variation) and the

Frequently debated areas of variability include cognitive ability, personality, physical appearance (body shape, skin color, etc.) and immunology.Variability is partly heritable and partly acquired (nature vs. nurture debate). Individuell biologisk variation Engelsk definition Differences in measurable biological values, characteristics, or traits, within one individual under different conditions for the individual such as fasting, season of the year, age, or state of wellness.

This has very interesting consequences for clinical investigation that are detailed elsewhere. How is it used in everyday practice? Biological variation is important for survival of individuals and species, and is the underpinning force behind evolution. The intricacies of human biology with its many layers of interconnecting networks and inbuilt redundancy evolved over many millions of years to maximize an individual's chance of survival. For an individual, this variation is due to the imprecision of the measurement procedure, that is to say the metrological variability, as well as to the rhythmic and random fluctuations of the quantity value around a virtual homeostatic set point, that is to say the intra-individual biological variability.

"Biological Variation, Individual" is a descriptor in the National Library of Medicine's controlled vocabulary thesaurus, MeSH (Medical Subject Headings).Descriptors are arranged in a hierarchical structure, which enables searching at various levels of specificity. Across the biological scales, variation explained by each level varied among leaf traits (Figure 2a). Specifically, variation explained by family varied across traits from 0% to 31.3%.

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.
