Research will focus on establishing the genetic basis of the between lake morphological differences in Bluegill populations. Larvae from in vitro crosses made with the Canadian study populations will be transported to "common garden" ponds at the University of Wisconsin-Milwaukee. These genetically marked individuals (with mtDNA and isozyme markers) will be reared in vegetated and open water habitats and their morphological development will be measured. This study will demonstrate unambiguously whether the inter-lake components of morphological divergence are due to underlying genetic variation or the result of environmental induction of phenotype working on a common, plastic genotype.

研究的重点是建立蓝鳃鱼种群间湖泊形态差异的遗传基础。与加拿大研究种群体外杂交的幼虫将被运送到威斯康星大学密尔沃基分校的“普通花园”池塘。这些遗传标记的个体（带有mtDNA和同工酶标记）将在植被和开阔水域生境中饲养，并测量其形态发育。这项研究将明确地证明湖泊间形态差异的组成部分是由于潜在的遗传变异还是由于环境诱导表型对共同的、可塑的基因型起作用的结果。
