The development of new molecular genetic and statistical techniques provides the opportunity to identify the number and genomic position of quantitative trait loci (QTL's) through linkage associations of variable molecular markers. These new techniques will be applied to a hybridization study of two species of crickets in the genus Laupala: L.paranigra and L.kohalaensis. These species posess an extremely simple acoustical communication system. Phenotypic variation in female phonotaxis will be associated to specific QTL's in a hybrid backcross design. These results will be compared to those obtained from another study on the male calling song in order to test competing models of genetic architecture of character covariation.

新的分子遗传学和统计技术的发展为通过可变分子标记的连锁关系来确定数量性状座位(QTL‘s)的数量和基因组位置提供了机会。这些新技术将被应用于月桂属两种蟋蟀的杂交研究：副蟋蟀和高哈拉蟋蟀。这些物种拥有一种极其简单的声音交流系统。在杂交回交设计中，雌性趋音性的表型变异将与特定的QTL相关。这些结果将与另一项关于雄性叫声的研究结果进行比较，以测试性格协变的遗传结构的竞争模型。
