Multiple paternity (MP) is a phenomenon observed for more than 30 elasmobranch species. The Batoidea is more specious than the Selachii, but only three studies of MP have been conducted on batoids. The occurrence of MP in freshwater stingrays was tested using microsatellite markers, which were developed for Potamotrygon leopoldi. Six mothers and their litters were genotyped, providing the first evidence of MP for Potamotrygonidae, with an MP frequency of 33%.
多父本(MP)现象在 30 多种软骨鱼纲物种中被观察到。板鳃亚纲比鲨形目更具多样性,但仅对 3 种鳐形目鱼类进行了多父本的研究。使用为 Potamotrygon leopoldi 开发的微卫星标记来测试淡水黄貂鱼中的多父本现象。对 6 位母亲及其幼崽进行了基因型分析,首次为 Potamotrygonidae 提供了多父本的证据,多父本频率为 33%。
