Ten narrative studies involving family histories of 262 children of gay fathers and lesbian mothers were evaluated statistically in response to Morrison's (2007) concerns about Cameron's (2006) research that had involved three narrative studies. Despite numerous attempts to bias the results in favour of the null hypothesis and allowing for up to 20 (of 63, 32%) coding errors, Cameron's (2006) hypothesis that gay and lesbian parents would be more likely to have gay, lesbian, bisexual or unsure (of sexual orientation) sons and daughters was confirmed. Percentages of children of gay and lesbian parents who adopted non-heterosexual identities ranged between 16% and 57%, with odds ratios of 1.7 to 12.1, depending on the mix of child and parent genders. Daughters of lesbian mothers were most likely (33% to 57%; odds ratios from 4.5 to 12.1) to report non-heterosexual identities. Data from ethnographic sources and from previous studies on gay and lesbian parenting were re-examined and found to support the hypothesis that social and parental influences may influence the expression of non-heterosexual identities and/or behaviour. Thus, evidence is presented from three different sources, contrary to most previous scientific opinion, even most previous scientific consensus, that suggests intergenerational transfer of sexual orientation can occur at statistically significant and substantial rates, especially for female parents or female children. In some analyses for sons, intergenerational transfer was not significant. Further research is needed with respect to pathways by which intergenerational transfer of sexual orientation may occur. The results confirm an evolving tendency among scholars to cite the possibility of some degree of intergenerational crossover of sexual orientation.
对涉及 262 名同性恋父亲和女同性恋母亲的孩子家庭史的 10 项叙述性研究进行了统计评估，以回应莫里森（2007）对卡梅伦（2006）研究的担忧，该研究涉及 3 项叙述性研究。尽管多次试图使结果偏向于零假设，并允许多达 20 个（63 个中的 20%）编码错误，但卡梅伦（2006）的假设得到了证实，即同性恋和女同性恋父母更有可能拥有同性恋、双性恋或不确定（性取向）的儿子和女儿。同性恋和女同性恋父母的孩子中，采用非异性恋身份的比例在 16%至 57%之间，取决于孩子和父母的性别组合，优势比在 1.7 至 12.1 之间。女同性恋母亲的女儿最有可能（33%至 57%；优势比从 4.5 到 12.1）报告非异性恋身份。对来自民族志来源和以前关于同性恋和女同性恋父母的研究的数据进行了重新审查，发现这些数据支持这样一种假设，即社会和父母的影响可能会影响非异性恋身份和/或行为的表达。因此，从三个不同的来源提供了证据，与大多数以前的科学观点，甚至大多数以前的科学共识相反，这表明性取向的代际传递可以以具有统计学意义和实质性的速度发生，特别是对于女同性恋父母或女同性恋孩子。在对儿子的一些分析中，代际传递并不显著。需要进一步研究代际性取向传递可能发生的途径。研究结果证实了学者们越来越倾向于引用性取向在某种程度上可能发生代际交叉的可能性。
