The heritability of neuroticism, one of the "big five" personality traits in humans, has been estimated to be 15%. This estimation was published by Power and Pluess in 2015. Assuming no interaction between genes and the environment, what can you conclude? Phenotypic variation of this trait stems mostly from environmental contributions. Genetic differences in the population account for much of the phenotypic variation for this trait. 15% of an individual's neuroticism is due to the genotype. Fifteen genes are contributing to the neuroticism trait. Neuroticism doesn't display phenotypic plasticity.
