Genetic variants linked to human personality have been identified
A meta-analysis involving over a million participants has identified more than a thousand genetic variants associated with human personality. The study, published today in the journal Nature, examines the possible links between DNA variations and differences in personality. The results do not suggest that personality can be predicted from DNA, but rather that some variants may influence behavioural traits, whilst acknowledging that other environmental factors may have a greater impact. In their work, the authors focus on five traits: extraversion, agreeableness, conscientiousness, neuroticism and openness to experience.
