Researchers analyzed the genomes and behavioral profiles of 1,300 golden retrievers and found that several behavioral traits-such as trainability, fear of strangers, and aggression toward other dogs-are shaped by specific genetic variants. Remarkably, a dozen of these same genes also influence emotional and cognitive traits in humans, revealing shared biological roots across species.
