Mapping the heritability of disease: a nationwide study [PDF]
Nature CommunicationsHeritability estimates are essential for understanding genetic and environmental contributions to disease, yet large-scale studies remain scarce. In this study, we leverage the Danish national health registers, including medical records for more than 10 ...

What does heritability of Alzheimer's disease represent?
PLoS ONE, 2023 IntroductionBoth late-onset Alzheimer's disease (AD) and ageing have a strong genetic component. In each case, many associated variants have been discovered, but how much missing heritability remains to be discovered is debated.

Optimal population size to detect quantitative trait loci in Korean native chicken: a simulation study [PDF]
Animal Bioscience, 2022 Objective A genomic region associated with a particular phenotype is called quantitative trait loci (QTL). To detect the optimal F2 population size associated with QTLs in native chicken, we performed a simulation study on F2 population derived from ...

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 ...
