A mailed questionnaire dealing with similarity in childhood, and how often and by whom the twins were mixed up, was applied to 290 same-sex adult twin pairs. For about 75% of pairs ten genetic markers were analysed. The agreement in zygosity classification between questionnaire and blood typing was high. Irrespective of whether raw scores of discriminant function analysis was applied, the agreement was nearly 95%. When a decision tree was applied, the percentage rose to nearly 96%. Considering that probably four of the twin pairs were wrongly classified as MZ by genetic markers, the percentage rose to 96 and 98, respectively.
一份关于童年相似性以及双胞胎被混淆的频率和混淆者的邮寄问卷被发放给了290对同性成年双胞胎。大约75%的双胞胎对被分析了10个基因标记。问卷和血型鉴定在合子性分类上的一致性很高。无论是否应用判别函数分析的原始分数，一致性都接近95%。当应用决策树时，这一百分比上升到了近96%。考虑到可能有4对双胞胎通过基因标记被错误地分类为同卵双胞胎，这一百分比分别上升到了96%和98%。
