Abstract
For further understanding the joint contribution of environment, heredity and gender to creativity, the present research examined the prospective impact of paternal indifference & neglect in early life, TPH1 rs623580, offspring gender, and the interaction effects thereof on creativity in five hundred and thirty-nine unrelated healthy Chinese undergraduate students. Paternal indifference & neglect in early life was assessed on the Parental Bonding Instrument (PBI) and creativity on the Runco Creativity Assessment Battery (rCAB). Two primary findings emerged. Firstly, significant paternal indifference & neglect × TPH1 genotype interaction effects were identified in predicting all three dimensions of creativity (fluency, originality, and flexibility). Paternal indifference & neglect in early life negatively predicted fluency, originality, and flexibility when individuals carry A allele of TPH1 (rs623580). Secondly, there was a significant interaction effect of TPH1 genotype by offspring gender on flexibility. Only in males, individuals who carry A allele were linked with lower level of flexibility compared to TT homozygote individuals. No significant three-way interaction was found. In conclusion, the current findings provided the first preliminary evidence for the moderation effect of TPH1 on the relationship between parenting and creativity, and TPH1- offspring gender interaction on creativity; future studies are needed to validate these findings.

Summary
Creativity is defined as the capacity for producing something that is both novel and useful [1,2,3]. Previous studies have indicated that creativity is the major driving forces behind the progress of civilization [5, 6]. How biological and environmental factors foster or inhibit creativity has long been a subject of great interest for psychologists [7, 8]. Recent advances in molecular genetics have permitted psychologists to explore the underlying genetic basis of creativity, and several genes (e.g. THP1, TPH2) have been reported to associate with creativity [9,10,11]. For the environmental factors, parenting has been one of the most frequently investigated topics due to its crucial role in creativity [12, 13].
