比较了3条河流中不同基因型和表型性别的马苏鲑（Oncorhynchus masou）在幼鱼和成鱼中的个体比例，发现成鱼中基因型雄性而表型雌性的个体比幼鱼多6-16%。这表明，在从少年到成年的过渡，基因型男性，但表型女性个体的存活率高于正常女性。与此相反，基因型女性，但表型男性的个人只发现在青少年时期，这表明他们表现出较低的生存率与正常男性相比。
The proportions of individual masu salmonOncorhynchus masouwhose genotypic and phenotypic sex differed were compared among juvenile and adult fish in three rivers, and genotypically male but phenotypically female individuals were observed 6–16% more often among adults than among juveniles. This suggests that during the transition from juvenile to adult, survival rates of genotypically male but phenotypically female individuals are higher than those of normal females. In contrast, genotypically female but phenotypically male individuals were only found in the juvenile period, which suggests that they exhibit a decreased survival rate in comparison with normal males.
