Is Cladogenesis Heritable? [PDF]

Systematic Biology, 2002
The heritability of speciation rates and extinction risks is a crucial parameter in models of macroevolution, but little direct evidence has been available to assess the occurrence, strength, or generality of this heritability. We tested for heritability using correlations between ancestral and descendent branch lengths in phylogenetic trees, an ...

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 ...

Homogenizing Estimates of Heritability Among SOLAR-Eclipse, OpenMx, APACE, and FPHI Software Packages in Neuroimaging Data

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

Effect of inbreeding on performance and genetic parameters of growth and survival traits in the Pacific oyster Crassostrea gigas at larval stage

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.

Spatially Dense 3D Facial Heritability and Modules of Co-heritability in a Father-Offspring Design

Frontiers in Genetics, 2018
Introduction: The human face is a complex trait displaying a strong genetic component as illustrated by various studies on facial heritability. Most of these start from sparse descriptions of facial shape using a limited set of landmarks.

Heritable and non-heritable uncommon causes of stroke

Journal of Neurology, 2020
Despite intensive investigations, about 30% of stroke cases remains of undetermined origin. After exclusion of common causes of stroke, there is a number of rare heritable and non-heritable conditions, which often remain misdiagnosed, that should be additionally considered in the diagnosis of cryptogenic stroke.

Estimating the heritability of psychological measures in the Human Connectome Project dataset.

PLoS ONE, 2020
The Human Connectome Project (HCP) is a large structural and functional MRI dataset with a rich array of behavioral and genotypic measures, as well as a biologically verified family structure. This makes it a valuable resource for investigating questions
