This study aimed to identify the genetic basis of dog stereotypes using single-nucleotide-polymorphism-based association mapping. The researchers genotyped 915 dogs from 80 breeds and used a mixed-model approach to identify significant associations between genetic markers and breed-typical behaviors. They found that certain behaviors, such as herding and pointing, were strongly associated with specific genetic markers, while others, such as aggression and fearfulness, were more complex and involved multiple genetic loci. The study also revealed that some breeds were more genetically diverse than others, which may have implications for breed health and welfare. Overall, this study provides important insights into the genetic basis of dog behavior and has implications for breed management and selection.
