Environmental variation (VE) in a quantitative trait–variation in phenotype that cannot be
explained by genetic variation or identifiable genetic differences–can be regarded as being …

Generating breeding programmes that effectively improve farmed fish performance across
multiple environments and make fish more uniform within production environments would …

Genotype-by-environment interaction (GEI) is a fundamental component in understanding
complex trait variation. However, it remains challenging to identify genetic variants with GEI …

Quantitative genetics has primarily focused on describing genetic effects on trait means and
largely ignored the effect of alternative alleles on trait variability, potentially missing an …

Many aspects of animal behaviour differ consistently between individuals, giving rise to the
growing field of animal personality research. While between‐individual variation has long …

Resilience is the capacity of an animal to be minimally affected by disturbances or to rapidly
return to the state pertained before exposure to a disturbance. Less resilient animals are …

The DMU-package for Analyzing Multivariate Mixed Models has been developed over a
period of more than 25 years. This paper gives an overview of new features and the recent …

Identification of genetic variants with effects on trait variability can provide insights into the
biological mechanisms that control variation and can identify potential interactions. We …

Traditional methods for detecting genes that affect complex diseases in humans or animal
models, milk production in livestock, or other traits of interest, have asked whether variation …

Myopia most often develops during school age, with the highest incidence in countries with
intensive education systems. Interactions between genetic variants and educational …
