Genetic Architecture of Tameness in a Rat Model of Animal Domestication
- BiologyGenetics
- 2009
Two significant quantitative trait loci (QTL) for tameness are identified that overlap with QTL for adrenal gland weight and for anxiety-related traits and are part of a five-locus epistatic network influencing tameness.

Genetic Influences on Brain Gene Expression in Rats Selected for Tameness and Aggression
- BiologyGenetics
- 2014
An F2 intercross of two outbred lines of rats selected for tame and aggressive behavior toward humans for >64 generations is studied, and four times more loci influencing tameness and aggression are identified than by an approach that assumes fixation of causative alleles.
Gene expression of behaviorally relevant genes in the cerebral hemisphere changes after selection for tameness in Red Junglefowl
- Biology, PsychologyPloS one
- 2017
It is concluded that five generations of divergent selection for high or low tameness has significantly changed gene expression patterns in the cerebral hemisphere in the Red Junglefowl population used here, which could underlie a range of changes in the domestic phenotype.
Interplay between aggression, brain monoamines and fur color mutation in the American mink
- Biology, PsychologyGenes, brain, and behavior
- 2016
Results provide the first experimental evidence of the interplay between aggression, brain monoamines and the Hedlund mutation in the American mink, which is an extreme case of depigmentation observed in domesticated animals.
The effects of prolonged selection for behavior on the stress response and activity of the reproductive system of male grey mice (Rattus norvegicus)
- Biology, PsychologyRussian Journal of Genetics
- 2014
This study is the first to characterize males recently caught in the wild with regard to the indices under consideration and used as a control group, and notes a higher glucocorticoid-mediated response to restriction stress and retarded sexual maturation in tame rats compared to aggressive ones, according to morphometric indices of gonads and testosterone levels.
Facial shape differences between rats selected for tame and aggressive behaviors
- BiologyPloS one
- 2017
Facial shape differences between the tame and aggressive rats were found that were independent of size and which mirrored changes seen in domesticated animals compared to their wild counterparts and there was no evidence of reduced sexual dimorphism in the face of the tame rats, indicating that certain phenotypic trends that are part of the domestication syndrome might not be consistently present in all experimental animal models.
The relationships between tameness and social cognitive skills of domesticated animals
- Psychology, BiologyJapanese Journal of Animal Psychology
- 2019
The relationship between tameness and social cognitive skills of domesticated animals, such as dogs, is explored and the possibility of the same brain regions being used in both conspecific and heterospecific interaction is discussed.
Effect of single ethanol administration on the behavior, consumption, and preference of ethanol in tame and aggressive rats
- Medicine, PsychologyRussian Journal of Genetics: Applied Research
- 2017
Assessment of the preferred consumption of ethanol at various concentrations with free access to ethanol and water and the effect of acute ethanol administration on the behavior of aggressive and tame male rats in an elevated plus maze finds an enhancement of anxiety-like behavior in tame rats.
