Abstract
Chromosomes of 21 sockeye salmon [Oncorhynchus nerka (Walbaum)] from three locations in Washington state were examined. All males had 57 chromosomes, while all females had 58 chromosomes. Both sexes had 104 chromosome arms. It appears that in males of this species the Y chromosome and an autosome have fused to form a metacentric chromosome.
摘要
对来自华盛顿州三个地点的21条红大马哈鱼（Oncorhynchus nerka (Walbaum)）的染色体进行了检查。所有雄性有57条染色体，而所有雌性有58条染色体。两性都有104条染色体臂。在该物种的雄性中，Y染色体和一条常染色体似乎已经融合形成了一条中着丝粒染色体。
