TL;DR
The influence of genetic factors for two personality dimensions was analyzed using data from 12,898 unselected twin pairs of the Swedish Twin Registry and found that about half the phenotypic variation may be attributed to genetic factors.
Abstract
The influence of genetic factors for two personality dimensions was analyzed using data from 12,898 unselected twin pairs of the Swedish Twin Registry. The heritability index was 0.50 (men) and 0.58 (women) for psychosocial instability. Corresponding figures for psychosocial extraversion were 0.54 and 0.66. Thus, about half the phenotypic variation may be attributed to genetic factors.

A biometrical-genetical analysis of twin data revealed that both genetical and environmental factors contributed to variation in extraversion, to the variation and covariation of its component scales, and to the interaction between subjects and scales.

A more penetrating analysis is needed of the extent to which variation in opinion and personality share a common genetic basis.

It has been shown that the factor of neuroticism is not a statistical artefact, but constitutes a biological unit which is inherited as a whole, and is perhaps as important as a demonstration that neurotic predisposition is to a large extent hereditarily determined.

The data suggested a contrast effect in which identical twins who were easily mistaken in appearance tended to be rated asless similar in personality, suggesting that similarity of appearance does not appear to bias twin studies in the direction of inflated heritabilities, at least for rating studies of the personality of young twins.

Responses of twins to an 11-item neuroticism scale extracted from questionnaires administered on two widely separated occasions were subjected to a genetic analysis and reveal that there is a genetic component in the inconsistency of the test measured by the interaction of subjects and test items.

The main reason for the establishment of a twin registry instead of using a representative sample from the entire population is that a twin population offers some additional analytical possibilities, and the registry is in many regards comparable with a registry of non-twins.

It was found that more than one genetical factor was probably involved in the determination of covariation among the E items, suggesting that the apparently unitary nature of extraversion at the phenotypic level could be due to environmental rather than togenetical influences.
