Veterinary behavioral genetics can greatly improve the welfare of pets in the future. However, it’s important to remember that genes are only part of an individual’s story. Behavior is a complex trait influenced by both the environment and multiple genes. Studies have shown associations between coat patterns, colors, and behavioral traits in dogs and cats. For example, red-coated English Cocker Spaniels were more likely to display aggression than black-coated dogs. However, defining and quantifying behavioral traits can be challenging, with some traits being more situational than others. Therefore, while genetic studies can provide useful insights, they should be used as a guide rather than a rule.
Key Takeaways:
- Veterinary behavioral genetics has the potential to improve the welfare of future generations of pets, but it’s important to remember that genes are only part of any individual’s story and behavior is also influenced by the environment.
- Behavior is complex and is not only influenced by the environment but also under polygenic control, meaning it’s controlled by the interaction of more than a single gene.
- Studies have found associations between coat patterns, colors, and behavioral traits in dogs and cats, but these findings highlight the need for consensus and limitations among behavioral studies.
“Behavior can be simplified as the product of an individual’s genotype multiplied by the environment. This is likely the most important concept to remember as we read the newest headlines about breeds, genes, and behavior. So, what should we do with the new information about behavior and genes that inundate media and our news feeds?”
