Genetic research into human sexuality was scarce at the end of last century. In 1992 Nick developed a 12-page questionnaire to send to twins to investigate the underpinnings of sexuality. The questionnaire included items about sexual orientation, sociosexuality and sexual behavior, and was completed by almost 5000 twins. The resulting data, unique at the time, has been used to investigate many previously unexaminable research questions. Here we describe how Nick’s questionnaire contributed to our understanding of human sexuality and how we got involved in this endeavor.

尼克·马丁对人类性研究的贡献

在上个世纪末，对人类性行为的基因研究很少。1992 年，尼克开发了一份 12 页的问卷，发送给双胞胎，以调查性行为的基础。问卷包括关于性取向、社会性行为和性行为的项目，由近 5000 名双胞胎完成。由此产生的数据在当时是独一无二的，已被用于调查许多以前无法检验的研究问题。在这里，我们描述了尼克的问卷如何有助于我们理解人类性行为以及我们如何参与这项工作。
