大象生活在一个以母系群体为基础的复杂社会中。管理圈养大象很困难，部分原因是每头大象都有独特的个性。为了更好地了解圈养大象的健康状况，系统地评估大象的个性及其潜在的生物学基础将是有帮助的。我们向75头大象的饲养员发出了大象个性问卷。我们还使用了196个大象DNA样本来搜索大脑中表达的基因的遗传多态，这些基因被认为与人格特征有关。雄激素受体(AR)、脆性X相关智力低下蛋白相互作用蛋白(NUFIP2)和Aheate-scute Homologs 1(ASH1)三个基因均含有多态区。我们研究了17头亚洲象和28头非洲象的个性与种内遗传变异的关系。结果表明，ASH1基因与亚洲象的神经质有关。短等位基因携带者的神经质得分低于长等位基因携带者。这是关于大象的基因多态与个性之间关系的第一份报告。动物园生物。2013年，32：70-78。©2012 Wiley期刊，Inc.
Elephants live in a complex society based on matrilineal groups. Management of captive elephants is difficult, partly because each elephant has a unique personality. For a better understanding of elephant well being in captivity, it would be helpful to systematically evaluate elephants' personalities and their underlying biological basis. We sent elephant' personality questionnaires to keepers of 75 elephants. We also used 196 elephant DNA samples to search for genetic polymorphisms in genes expressed in the brain that have been suggested to be related to personality traits. Three genes, androgen receptor (AR), fragile X related mental retardation protein interacting protein (NUFIP2), and acheate‐scute homologs 1 (ASH1) contained polymorphic regions. We examined the association of personality with intraspecific genetic variation in 17 Asian and 28 African elephants. The results suggest that theASH1genotype was associated with neuroticism in Asian elephants. Subjects with short alleles had lower scores of neuroticism than those with long alleles. This is the first report of an association between a genetic polymorphism and personality in elephants. Zoo Biol. 32:70‐78, 2013. © 2012 Wiley Periodicals, Inc.
