Objective: This paper examines to what extent genetic and environmental influences contribute to differences in family leisure activities of girls and boys. Background: While family leisure activities have been described as relevant for child development, it remains unclear what accounts for differences in the leisure behavior of girls and boys. While research emphasized the importance of the environment, e.g., in relation to gender role socialization, other studies pointed to biological and, thus, genetic differences as explanatory factors. Method: The analysis is based on 954 female and 1036 male twins aged 10-12 years who are part of the first wave of the German Twin Family Panel Study. Our analysis examines five family leisure activities using variance decompositions and gene-environment interaction models. Results: Overall, there were only minor differences between girls and boys in the contributions of genes and environments to family leisure activities. Only for singing and making music did influences from the environment common to both twins contribute more strongly to the performance of these activities in the girls than in the boys. Conclusion: There is no evidence that genetic differences lead to differences in family leisure behavior between girls and boys in the activities considered here. Existing differences are more likely to be due to environmental influences.
