Ant cuticular hydrocarbons are heritable and associated with variation in colony productivity
In social insects, cuticular hydrocarbons function in nest-mate recognition and also provide a
waxy barrier against desiccation, but basic evolutionary features, including the heritability of …

The genetic architecture of socially-affected traits: a GWAS for direct and indirect genetic effects on survival time in laying hens showing cannibalism
Background Cannibalism is an important welfare problem in the layer industry. Cannibalism
is a social behavior where individual survival is affected by direct genetic effects (DGE) and …

[HTML][HTML] Can breeders solve mortality due to feather pecking in laying hens?
Mortality due to feather pecking (FP) has large economic and welfare consequences in the
commercial poultry industry, and reduces survival of birds. With FP, the survival time of a hen …

Models with indirect genetic effects depending on group sizes: a simulation study assessing the precision of the estimates of the dilution parameter
Background In settings with social interactions, the phenotype of an individual is affected by
the direct genetic effect (DGE) of the individual itself and by indirect genetic effects (IGE) of …

Statistical model and testing designs to increase response to selection with constrained inbreeding in genomic breeding programs for pigs affected by social genetic …
Background Social genetic effects (SGE) are the effects of the genotype of one animal on the
phenotypes of other animals within a social group. Because SGE contribute to variation in …
