Heritability of Personality [PDF]
Psychological Topics, 2017 The aim of this study is to simplify the issue of the concept of heritability, to give an introduction to the behavioral genetic theory and methods, as well as to give an overview of the current knowledge about heritability of personality and the ...

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 ...

Heritability estimation of osteoarthritis in the pig-tailed macaque (Macaca nemestrina) with a look toward future data collection [PDF]
PeerJ, 2014 We examine heritability estimation of an ordinal trait for osteoarthritis, using a population of pig-tailed macaques from the Washington National Primate Research Center (WaNPRC).

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 misspecification ...

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

The heritability of attractiveness [PDF]
Current Biology, 2007 SummarySexual selection is responsible for the evolution of numerous conspicuous and extravagant displays observed in nature — from cricket choruses to peacock's tails. A key assumption of many models of sexual selection is that attractive males father attractive sons1.

Using extended genealogy to estimate components of heritability for 23 quantitative and dichotomous traits. [PDF]
PLoS Genetics, 2013 Important knowledge about the determinants of complex human phenotypes can be obtained from the estimation of heritability, the fraction of phenotypic variation in a population that is determined by genetic factors.
