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.
利用瑞典双胞胎登记处12898对未经挑选的双胞胎的数据,分析了基因因素对两个人格维度的影响。心理社会不稳定性的遗传率指数男性为0.50,女性为0.58。心理社会外向性的相应数字分别为0.54和0.66。因此,约一半的表型变异可能归因于基因因素。
