Abstract
The thermal stabilities of hybrid duplexes between the DNAs from three salmonid fish species were monitored as measures of DNA homology. The chum salmon, Oncorhynchus keta, and coho salmon, Oncorhynchus kisutch, had more DNA homology with each other than either had with the rainbow trout, Salmo gairdnerii. Morphological, ecological and protein similarities between the coho salmon and the rainbow trout may be due to parallel or convergent evolution.
摘要
监测了三种鲑科鱼类的DNA之间杂交双链体的热稳定性，以此作为DNA同源性的衡量指标。大麻哈鱼（Oncorhynchus keta）和银大麻哈鱼（Oncorhynchus kisutch）之间的DNA同源性高于它们与虹鳟（Salmo gairdnerii）的DNA同源性。银大麻哈鱼和虹鳟在形态、生态及蛋白质方面的相似性可能是平行进化或趋同进化的结果。
