Heritability in Morphological Robot Evolution [PDF]
arXiv, 2021 In the field of evolutionary robotics, choosing the correct encoding is very complicated, especially when robots evolve both behaviours and morphologies at the same time. With the objective of improving our understanding of the mapping process from encodings to functional robots, we introduce the biological notion of heritability, which captures the ...

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 ...

Relative abundance data can misrepresent heritability of the microbiome
Microbiome, 2023 Background Host genetics can shape microbiome composition, but to what extent it does, remains unclear. Like any other complex trait, this important question can be addressed by estimating the heritability (h 2 ) of the microbiome—the proportion of ...

How to estimate heritability, a guide for epidemiologists [PDF]
arXiv, 2021 Traditionally, heritability has been estimated using family-based methods such as twin studies. Advancements in molecular genomics have facilitated the development of alternative methods that utilise large samples of unrelated or related individuals.

Subsampling Technique to Estimate Variance Component for UK-Biobank Traits
Frontiers in Genetics, 2021 The estimation of heritability has been an important question in statistical genetics. Due to the clear mathematical properties, the modified Haseman–Elston regression has been found a bridge that connects and develops various parallel heritability ...

Estimation of heritability and genetic advance for various metric traits in seven F2 populations of bread wheat (Triticum aestivum L.) [PDF]
Journal of Agricultural Sciences (Belgrade), 2016 Heritability estimates provide information about the traits that are transmitted from parents to their offsprings and it has a crucial role in selection criteria to improve grain yield.

The Mahalanobis kernel for heritability estimation in genome-wide association studies: fixed-effects and random-effects methods [PDF]
arXiv, 2019 Linear mixed models (LMMs) are widely used for heritability estimation in genome-wide association studies (GWAS). In standard approaches to heritability estimation with LMMs, a genetic relationship matrix (GRM) must be specified. In GWAS, the GRM is frequently a correlation matrix estimated from the study population's genotypes, which corresponds to a ...

Optimal Estimation of Co-heritability in High-dimensional Linear Models [PDF]
arXiv, 2016 Co-heritability is an important concept that characterizes the genetic associations within pairs of quantitative traits. There has been significant recent interest in estimating the co-heritability based on data from the genome-wide association studies (GWAS).
