A new study suggests that genes play a significant role in shaping the behavior of worker bees, influencing their roles within the hive. Researchers found that the 'doublesex' gene, crucial for sex determination in many species, is also essential for coordinating social behaviors in bees.
New evidence reveals that behavior may be predetermined by genetics. Generally, we consider behavior to be learned. By interacting with the world, different behaviors are reinforced or discouraged. A student who receives a high grade on a test will be more motivated to study and continue performing well. The reward of these habits creates a positive feedback loop. Studies suggest that our genes also influence our behaviors.
Genetics also plays a role in how we interact with each other. The oxytocin receptor gene and vasopressin receptor gene have been shown to mediate bonding behavior in various species, including humans. Variants in the oxytocin receptor gene, in fact, have been linked to autism spectrum disorder and depression. How an individual responds during a specific social experience, however, involves a complex interplay of genes and environmental factors.
Bee colonies have a unique social structure split into three castes: the queen, workers, and drones. The all-male drone bees generally leave the hive to mate with queens in other colonies. Female bees, therefore, perform the vast majority of tasks in the hive. Only one female bee, however, is queen. The remaining are infertile worker bees. Whether a female becomes a queen and a worker bee is influenced by a gene calledgene, which mediates the female developmental pathway.
