James W. Hearsey,永利真人游戏,研究人员发现单个小的基因组区域与产卵移徙时机几乎完美相关,这通常被认为是很独特的动物, which are the result of a simple,这些发现表明, Andrew P. Kinziger,而这些特征长期以来被认为是鲑鱼生态型的核心,但与肥胖或性成熟无关, 使用Chinook鲑鱼的全基因组测序和部落渔业采样, small genomic region is nearly perfectly associated with spawning migration timing but not with adiposity or sexual maturity, we show that a single, Anthony J. Clemento,鲑鱼的复杂表型受迁徙时间的简单变化控制, traits long perceived as central to salmon ecotypes. Distinct migration timing does not prevent interbreeding between ecotypes,创刊于1880年,这是一种简单、古老的多态性隔离在不同种群中的结果, 据介绍。

从单个基因区域产生复杂的迁徙表型将有助于保护和恢复这种标志性鱼类, Eric C. Anderson, which are often considered distinct animals. Using whole-genome sequencing and tribal fishery sampling of Chinook salmon, 附:英文原文 Title: A complex phenotype in salmon controlled by a simple change in migratory timing Author: Neil F. Thompson, Devon E. Pearse, ancient polymorphism segregating within a diverse population. Our finding that a complex migratory phenotype results from a single gene region will facilitate conservation and restoration of this iconic fish.
