摘要：巴拿马博卡斯德尔托罗群岛的岛屿和大陆地区的 Dendrobates pumilio（草莓毒蛙）种群在颜色和颜色图案上表现出极大的差异。先前的分析表明，这些不同的种群可能是同一物种的成员。在这里，我们提供了几种不同颜色和颜色图案变形之间的杂交数据。来自七个种群的不同变体之间进行了成功的杂交：博卡斯岛、南希岛、波普岛、巴斯蒂门托斯岛以及大陆上的阿尔米兰特岛、兰巴拉岛和阿瓜卡特半岛。对所得后代的颜色和颜色图案进行了表征。我们的研究表明，不同颜色的变种可以杂交产生可存活的后代。后代通常会显示出混合颜色，但如果父母之一显示颜色模式，则总是显示颜色模式。这表明颜色模式处于具有显性的单基因座控制之下，而着色可能处于多基因控制之下，或者可能代表具有不完全显性的单基因座系统。
Abstract Populations ascribed to Dendrobates pumilio, the Strawberry Poison Frog, show extreme variation in color and color pattern among island and mainland locations in the Bocas del Toro Archipelago in Panama. Previous analyses indicate that these different populations are probably members of a single species. Here we present data on crosses between several different color and color pattern morphs. Successful crosses were made between different morphs from seven populations: Bocas Island, Nancy Cay, Pope Island, Bastimentos Island, and Almirante, Rambala and the Aguacate Peninsula on the mainland. The resulting offspring were characterized for color and color pattern. Our study indicates that different color morphs can interbreed to produce viable offspring. The offspring typically displayed a mixture of colors but always showed color pattern if one parent showed color pattern. This suggests that color pattern is under single locus control with dominance, whereas coloration may be under polygenic control, or may represent a single locus system with incomplete dominance.
