In order to arrive at detailed information about the occurrence of alternative reproductive tactics in the great tit (Parus major) we examined parental lineages by multilocus fingerprinting in 51 great tit broods containing 429 nestlings. In 45% of the broods at least one nestling was found to stem from copulations with males other than the social mate of the female. Single broods contained up to 62% extra-pair young (EPY). Single locus profiling revealed how many fathers were involved in extra-pair paternity (EPP) within each brood: In most cases a single male is the genetic father of all EPY in a given brood.
为了获取关于大山雀（Parus major）中替代繁殖策略发生情况的详细信息，我们通过多位点指纹识别技术，对51窝共429只大山雀雏鸟的亲系进行了检测。在45%的窝中，至少有一只雏鸟被发现并非来自雌鸟的社会配偶，而是与其他雄鸟交配所生。单个窝中额外配对子代（EPY）的比例高达62%。单一位点分析揭示了每窝中涉及额外配对父权（EPP）的父鸟数量：在大多数情况下，单个雄鸟是特定窝中所有EPY的基因父亲。
