Behavioral Genetics on Animal Studies - Dictionary of Arguments

Corr I 292
Animal studies/behavioral genetics/Munafò: [animal studies] offer several attributes useful in genetic research, including short gestation, early puberty and large litters, as well as a greater degree of experimental control, by means of directed mating and environmental control, all of which are valuable when attempting to map the genetic architecture of these traits (Willis-Owen and Flint 2007)(1).
The basic experimental design is the analysis of association between genotypic and phenotypic variation in a cross between two inbred strains of rodents (usually, but not necessarily, with contrasting temperament phenotypes).
Molecular genetic markers are then used to determine which chromosomal segments segregate with the trait (that is, which chromosomal regions are shared by animals that are phenotypically similar for the trait of interest). Over the past ten years, QTL (quantitative trait loci) putatively related to temperament have been identified on a number of chromosomes, although the molecular nature of these remains unclear.
