Heritabilities and quantitative trait loci for blood gases and blood pH in swine
Animal Genetics, 2009SummaryMaintaining pH and blood gases in a narrow range is essential to sustain normal biochemical reactions. Decreased oxygenation, poor tissue perfusion, disturbance to CO2 expiration, and shortage of HCO3− can lead to metabolic acidosis. This is a common situation in swine, and originates from a broad range of medical conditions.

Heritability of quantitative traits
1995Abstract In the most traditional view, heritability is the proportion of total phenotypic variance attributable to additive genetic variance. The latter results from segregation of alleles with additive effects. Other contributors to total variance include dominance, epistatic and environmental effects and covariances and interactions ...

HERITABILITY OF A QUANTITATIVE COTTON TRAIT IN HYBRID POPULATIONS F2
2023The article presents analysis of heritability estimate by a raw cotton boll mass in a population of geographically separated cotton F2 hybrids. Efficacy of selection by a raw cotton boll mass was demonstrated to depend on individual peculiarities of the genotypes hybridized.

Heritability of some quantitative traits in winter wheat
1998Broad and narrow sense heritability estimates were otained for 11 traits in 15 winter wheat combinations of crossing (Triticum aestivum L.) In seven combinations of crossing a high mean value was found for a large number of traits and moderately high to high broad and/or narrow sense heritability estimates.

AbstractThe use of skeletal nonmetric traits in studies of biological relationships often involves the assumption that variation in these traits is genetic. Studies of nonmetric traits in human groups and in inbred strains of mice and rabbits have indicated a genetic component to nonmetric trait variation.

Identifying genetic variation underlying a complex disease is important. Many complex diseases have heterogeneous phenotypes and are products of a variety of genetic and environmental factors acting in concert. Deriving highly heritable quantitative traits of a complex disease can improve the identification of genetic risk of the disease.

AbstractDespite evidence for several chromosomal loci linked to schizophrenia, no susceptibility genes have been identified for the disorder. Using quantitative measures of phenotypic affection in place of clinical diagnostic categories or dichotomous classification of the affection status may be more effective in searching for susceptibility genes ...

Human Heredity, 2006
<i>Background/Aims:</i> In genome-wide linkage analysis ofquantitative trait loci (QTL), locus-specific heritability estimates are biased when the original data are used to both localize linkage and estimate effects, due to maximization of the LOD score over the genome. Positive bias is increased by adoption of stringent significance levels

Heritability of quantitative traits in segregating common bean families using a Bayesian approach
Euphytica, 2008Genetic parameters for six quantitative traits in the early generation of segregating populations of common beans (Phaseolus vulgaris L.) were evaluated. A Bayesian approach was used for estimating the variance components, breeding values and broad sense heritability of the quantitative traits under analysis.
