From the trajectory of heritability to the heritability of trajectories
Behavioral and Brain Sciences, 2021 Abstract Although compelling and insightful, the proposal by Uchiyama et al. largely neglects within-person change over time, arguably the central topic of interest within their framework. Longitudinal behavioural genetics modelling suggests that the heritability of trajectories is low, in contrast to high and increasing cross-sectional heritability

On Negative Heritability and Negative Estimates of Heritability [PDF]
Genetics, 2017 Abstract We consider the problem of interpreting negative maximum likelihood estimates of heritability that sometimes arise from popular statistical models of additive genetic variation. These may result from random noise acting on estimates of genuinely positive heritability, but we argue that they may also arise from ...

Heritability of endometriosis [PDF]
Fertility and Sterility, 2015 To estimate the relative contribution of genetic influences and prevalence on endometriosis.Analysis of self-reported data from a nationwide population-based twin registry.Not applicable.A total of 28,370 women, female monozygotic (MZ) or dizygotic (DZ) twins, who participated in either of two surveys (1998-2002 or 2005-2006).None.Self-reported ...

Frontiers in Neuroinformatics, 2019 Imaging genetic analyses use heritability calculations to measure the fraction of phenotypic variance attributable to additive genetic factors. We tested the agreement between heritability estimates provided by four methods that are used for heritability

Statistical methods for SNP heritability estimation and partition: A review
Computational and Structural Biotechnology Journal, 2020 In GWAS studies, SNP heritability measures the proportion of phenotypic variance explained by all measured SNPs. Accurate estimation of SNP heritability can help us better understand the degree to which measured genetic variants influence phenotypes ...

Heritability of scoliosis [PDF]
European Spine Journal, 2011 To estimate the heritability of scoliosis in the Swedish Twin Registry.Self-reported data on scoliosis from 64,578 twins in the Swedish Twin Registry were analysed. Prevalence, pair- and probandwise concordances and tetrachoric correlations in mono- and dizygotic same-sex twins were calculated. The relative importance of genetic variance, i.e.

Aquaculture Reports, 2021 The occurrence of inbreeding over generations cannot be avoided in breeding practice because of limited effective population sizes, and inbreeding is expected to decrease the heritability within populations.

Phenome-wide heritability analysis of the UK Biobank.
PLoS Genetics, 2017 Heritability estimation provides important information about the relative contribution of genetic and environmental factors to phenotypic variation, and provides an upper bound for the utility of genetic risk prediction models.
