Five genes that affect sociality-related behaviour in chickens have been identified by researchers at Linköping University in Sweden. Several of the genes have been previously linked to nervous system function or behaviour. The new study, which is published in Genetics, is the first that assigns these genes a role in sociality.
Sociality and social behaviour covers a wide range of behaviours. Dogs seeking human contact and honeybees using complex waggle dances to exchange information on where to find good food sources are two examples from the animal world. But what actually governs social behaviour?
"By identifying the genes responsible for the variation in such sociality we can understand how sociality is formed and how social behaviour is controlled at a genetic level. Why some people or animals are more gregarious by nature and others more independent is just one such example," says Dominic Wright, senior lecturer at the Department of Physics, Chemistry and Biology (IFM), who has led the study.
