Times-to-death (TTD) of mother and offspring mosquitofish (Gambusia holbrooki) were examined during acute exposure to mercury concentrations of approximately 1.0 mg/L. Median TTD were more similar for fish sharing a common mother (defined herein as a sibship) and microhabitat during maturation than between sibships. Field populations may exhibit structure similar to that of these sibships. Correlations between broods (or other population subunits) and allozyme genotype could be responsible for transient, genotype effects noted during electrophoretic surveys attempting to measure population level response to toxicants.
在急性暴露于约1.0毫克/升汞浓度的情况下，对母本和后代食蚊鱼（盖氏食蚊鱼）的死亡时间（TTD）进行了研究。在成熟过程中，共享同一母本（本文定义为一个同胞群）和微生境的鱼类的中位TTD比不同同胞群之间的更相似。野外种群可能表现出与这些同胞群相似的结构。在试图测量种群对毒物水平反应的电泳调查中，观察到的短暂基因型效应可能是由不同窝（或其他种群亚单位）与等位酶基因型之间的相关性导致的。
