A statistical estimate of the fraction of observed measure of the overall amount of difference among people in a population that is caused by differences in heredity. go to glossary index
the extent to which a trait is influenced by our genetic makeup.
the extent to which variability in a characteristic within a group can be attributed to heredity. (109, 365)
The portion of the total variation or phenotypic differences among animals that is due to heredity.
The proportion (fraction) of difference among animals for a trait, such as milk production, due to genetic difference rather than environmental factors. The fraction of variation in a trait that is genetically transmissible from parent to offspring.
The amount of variation of a particular trait within a population that is caused by genetic, as opposed to environmental, differences.
In the broad sense, the proportion of the total phenotypic variance which is inherited, the remainder being due to environmental effects. In the narrow sense, the proportion of variance due to additive effects of genes.
Statistical estimate of contribution of heredity to individual differences in a trait within a given population. (52)
The extent to which a trait is genetically determined.
A term that describes the proportion of phenotypic variation among individuals in a specific population that can be attributed to genetic effects. Heritability is a characteristic of a population, not of an individual, and is an estimate of the relative importance of genetic influences on a trait (as opposed to environmental influences).
The proportion of the variation in a given characteristic or state that can be attributed to genetic factors.
The proportion of the total phenotypic variation in a trait that can be attributed to additive genetic effects. Heritabilities are standardized measures, taking on values from zero (no genetic variation contributing to phenotypic variation in the population) to one (all of the variation in the population reflects genetic differences).
The proportion of the total phenotypic variance that is attributable to genetic causes (h2= genetic variance / total phenotypic variance).
The degree to which traits are passed from parent to offspring.
That portion of a trait which can be inherited. (Example: Hip dysplasia is not 100% heritable because environmental conditions can affect its expression.) Also, the degree of variation which can be influenced by heredity. (Example: All Skipperkies are black and black color is inherited, but the heritability of black in Skipperkies is 0% because they are all homozygous for the trait and there is no variation.)
Statistical estimate of variation in a trait that is attributable to genetic differences among individuals within a group. It is commonly expressed as a proportion.
The capability of a trait being passed from one generation to the next
The extent to which a particular trait is inherited. A trait that is entirely genetic, e.g. eye colour, has a heritability of one, whereas something entirely environmental, e.g. presence of tattoos, has a heritability of zero.
can be genetically inherited.
The proportion of total phenotypic variance at the population level that is contributed by genetic variance (also called heritability in the broad sense). Heritability in the narrow sense: The proportion of phenotypic variance that can be attributed to additive genetic variance.
In the narrow sense: 1. the proportion of phenotypic superiority of parents that is seen in their offspring; 2. the proportion of the total phenotypic variation due to variation in breeding values. In the broad sense: the proportion of the total phenotypic variation due to genetic variation. The degree to which a given trait is controlled by inheritance. See broad-sense heritability; narrow-sense heritability.
The proportion of the total phenotypic variation of a trait that has a genetic basis.
The proportion of observed variation in a particular trait that can be attributed to inherited genetic factors in contrast to environmental ones.
The proportion of variability of a character due to heredity, the remainder being due to environment. In a broad sense, that portion of the total variance due to all genetic factors. In a narrow sense, that portion of the total variance due to genes with additive effects and most indicative of the superiority that can be transmitted by sexual propagation. Heritability, family - That portion of the total variance due to differences among families, and applicable only to family means.
proportion of trait variance attributable to genetic factors
The transmission of characteristics, or proportions of characteristics, from parent to offspring via the sex cells. Some characteristics or diseases have a higher heritability than others.
The degree to which a characteristic is determined by genetics
the fraction of the variability in a trait that is caused by genetic differences
the degree to which a trait, such as excess body fat, can be explained by genetic factors.
The proportion of the differences among individuals, measured or observed, that is transmitted to the offspring. Heritability varies from zero to one. The higher the heritability of a trait, the more accurately the individual performance predicts breeding value and the more rapid should be the response due to selection for that trait.
A measure of the strength of the relationship between performance (phenotypic values) and breeding values for a trait in a population. Heritability in the broad sense.
an attribute of a quantitative trait in a population that expresses how much of the total phenotypic variation is due to genetic variation
A measure of the degree to which observed phenotypic differences for a trait are genetic.
in the narrow sense, heritability is defined as the proportion of the total phenotypic variance in a trait that is due to the additive effects of genes, as opposed to dominance or environmental effects. In the broad sense, heritability is proportion of the total phenotypic variance of a trait that is due to all genetic effects, including additive and dominance effects. [Source: NHBLI/NCBI Glossary
The proportion of variation in a trait among individuals in a population that can be attributed to genetic effects.
Extent to which an animal characteristics or traits are passed on to future generations.
A measure of the degree to which a phenotype is genetically determined.
A measurement of the extent to which individual genetic differences contribute to individual differences in observed behaviour.
The degree to which the phenotype (expression of a trait that you can measure, or describe like how much milk, or what color hair) of an animal is likely to predict the expression of that trait in the offspring of the animal. How likely is it for a cow that produces a lot of milk to have a daughter that produces a lot of milk
The proportion of parental superiority which is transmitted to the offspring. The heritability can vary from 0-100%. Traits of high heritability are those above 50%, medium from 20-50% and low are below 20%.
The proportion of the total variability of a trait in a given population that is attributable to genetic differences among individuals within the population.
Proportion of variability in the phenotype that is estimated to be accounted for by genetic influences within a known environmental range.
The proportion of the total variation of a character attributable to genetic as opposed to environmental factors.
In genetics, heritability is the proportion of phenotypic variation in a population that is attributable to genetic variation among individuals. Variation among individuals may be due to genetic and/or environmental factors. Heritability analyses estimate the relative contributions of differences in genetic and non-genetic factors to the total phenotypic variance in a population.
