Abstract

For many species, migrating at just the right time is essential for both survival and reproduction. A new study in salmon localizes a small genomic region associated with migration timing, which in turn affects other physiological traits, suggesting that a seemingly complex suite of migration traits is linked by one "simple" phenotype.

摘要

对于许多物种来说，在恰当的时间迁徙对于生存和繁殖都至关重要。一项针对鲑鱼的新研究定位了一个与迁徙时间相关的小基因组区域，该区域进而影响其他生理特征，这表明一系列看似复杂的迁徙特征是由一个“简单”的表型联系起来的。
