Why is genetic diversity important in bee populations?

Genetic diversity in bee populations plays a crucial role in enhancing disease resistance and the overall resilience of the colony. A genetically diverse population of bees allows for a wider range of immune responses to be present among individuals, which can help the colony resist various pathogens and diseases. This diversity increases the chances that at least some members of the colony will possess genetic traits that confer resistance to emerging threats, leading to a healthier colony capable of surviving environmental stresses and challenges.

Furthermore, in a genetically diverse population, behaviors that promote foraging efficiency, reproduction, and overall adaptability to changing conditions are often more pronounced. This collective resilience ensures the colony can thrive in fluctuating environments and withstand pressures such as climate change or loss of habitat.

While other options mention aspects related to bee behavior and productivity, they do not adequately address the critical role of genetic diversity in ensuring a colony's health and ability to cope with disease.
