定量遗传学研究经常利用动物的近交系作为工具，将基因的直接和间接影响与环境影响分开，以产生观察到的表型，然而，这种方法很少应用于行为研究。孔雀鱼（Poecilia reticulata）执行一系列反捕食者行为，这可能为研究复杂行为特征是如何产生的提供一个理想的系统。为了评估观赏孔雀鱼在行为定量遗传学研究中的效用，我们分析了五种形态不同的观赏孔雀鱼品系对捕食者线索的反应以及品系之间反应的变化。尽管存在个体差异，但所有五种品系都对捕食者的线索做出了反应，并且在所有分析的行为中都发现了品系之间的差异，包括勇气和躲避捕食者的措施。
Quantitative genetic studies frequently utilize inbred strains of animals as tools for partitioning the direct and indirect effects of genes from environmental effects in generating an observed phenotype, however, this approach is rarely applied to behavioral studies. Guppies, Poecilia reticulata, perform a set of anti-predator behaviors that may provide an ideal system to study how complex behavioral traits are generated. To assess the utility of ornamental guppies in quantitative genetics studies of behavior, we assayed five morphologically distinct strains of ornamental guppies for response to predator cues and for variation in response among strains. Despite individual variation, all five strains responded to predator cues and differences among strains were found for all assayed behaviors, including measures of boldness and predator avoidance.
