Assuming Dr. Wagoner's work proves accurate and affordable, it may simplify selection for hygienic behavior. During a video segment, she distinguished between a colony's ability to produce unhealthy brood odor and workers' ability to detect that odor as if uncapping and removal are genome-based, but odor production isn't. Unless unhealthy brood odor is strictly environmental, I would think both are genetic. But if unhealthy brood order results from environmental conditions, it's a variable that would complicate the application.
