Variance components,heritability estimates,and breeding values for performance test traits in Old Kladruber horses
harness horse genetic parameters performance test genetic resource
2016/9/1
The Old Kladruber horse is an important Czech genetic resource. In the current study, two categories of traits were evaluated – the first, a numerical score for Type and Gender Expression and the seco...
Heritability of high sugar consumption through drinks and the genetic correlation with substance use
addiction genetics substance use sugar consumption twin study
2018/12/14
Background: High sugar consumption contributes to the rising prevalence of obesity. Sugar can have rewarding effects that are similar to, but less strong than, the effects of addictive substances. Peo...

How much do we know about the heritability of BMI?
heritability of BMI obesity heritable contribution of genetics
2018/12/3
Is obesity heritable? Like father, like son; like mother, like daughter—scientists have no doubt about it. But how great is the contribution of genetics compared with environmental influence? Many twi...

How to read “heritability” in the recipe approach to natural selection
heritability recipe approach natural selection
2016/6/12
There are two ways evolution by natural selection (ENS) is conceptualized in the literature. One provides a ‘recipe’ for ENS incorporating three ingredients: variation, differences in fitness and heri...
Heritability of hyperresponsivity of brain reward regions to high-calorie food
Heritability hyperresponsivity of brain region high-calorie food
2018/11/27
Numerous studies have found that obese compared with lean individuals show greater response of brain regions implicated in reward [e.g., orbitofrontal cortex (OFC), striatum, amygdala] when viewing im...
We show in an idealized model that the narrow sense (linear) heritability from d autosomal SNPs can be estimated without bias from n independently sampled individuals, by a method of moments strategy ...
Heritability of egg production in laying hens under cumulative, multitrait and repeated measurement animal models
egg production laying hens cumulative model monthly records
2015/6/4
Six generations of three layer lines (13 770 recorded individuals of A22 line, 13 950 of A88, 9 351 of K66) were used to estimate genetic effects on egg production under cumulative, multitrait and rep...
Breeding value evaluation in Polish fur animals: Estimates of direct heritability and portion of litter variation of fur coat and reproduction traits
arctic fox fur coat heritability
2015/6/1
The study presents estimates of heritability for fur coat and reproduction traits in arctic and silver foxes kept on Polish farms. The estimates of variance components were calculated using the DFREML...
Heritability of Flowering Time within Apple Progeny
apple breeding flower set Malus × domestica
2015/4/1
The flowering onset of 19 apple progeny was evaluated in 2005–2014 on a total number of 715 seedlings in
comparison with their parents and grandparents. A very low flower set delays generally t...
Variability, heritability and correlations of some factors affecting productivity in peach
Prunus persica flower density fruit set
2015/3/3
Factors affecting productivity in peach, such as flower density, initial and final fruit set by open pollination, and yield per m length of shoot were studied in 40 cultivars during a three-year perio...
Heritability of Lumbar Trabecular Bone Mechanical Properties in Baboons
mechanical properties nonhuman primate skeletal genetics
2014/12/4
Genetic effects on mechanical properties have been demonstrated in rodents, but not confirmed in primates. Our aim was to quantify the proportion of variation in vertebral trabecular bone mechanical p...
Genomic Heritability of Bovine Growth Using a Mixed Model
Bovine Genome Growth Heritability Mixed Model Single Nucleotide Polymorphism
2016/5/17
This study investigated heritability for bovine growth estimated with genomewide single nucleotide polymorphism (SNP) information obtained from a DNA microarray chip. Three hundred sixty seven Korean ...
Narrowing the gap on heritability of common disease by direct estimation in case-control GWAS
Narrowing the gap heritability common disease direct estimation case-control GWAS
2013/6/17
One of the major developments in recent years in the search for missing heritability of human phenotypes is the adoption of linear mixed-effects models (LMMs) to estimate heritability due to genetic v...
