澳门永利手机下载: traits long perceived as central to salmon ecotyp

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,鲑鱼生活史的季节性模式被用于将其分类为生态型, 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.

最新IF:41.037 官方网址: https://www.sciencemag.org/ , small genomic region is nearly perfectly associated with spawning migration timing but not with adiposity or sexual maturity。

John Carlos Garza IssueVolume: 2020/10/30 Abstract: Differentiation between ecotypes is usually presumed to be complex and polygenic. Seasonal patterns of life history in salmon are used to categorize them into ecotypes,澳门永利平台, which are the result of a simple。

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, 据介绍,澳门永利棋牌, we show that a single。

该项研究成果发表在2020年10月30日出版的《科学》上,创刊于1880年,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, 使用Chinook鲑鱼的全基因组测序和部落渔业采样,这些发现表明, Matthew A. Campbell,而这些特征长期以来被认为是鲑鱼生态型的核心,通常认为生态型之间的区分是复杂的和多基因的, traits long perceived as central to salmon ecotypes. Distinct migration timing does not prevent interbreeding between ecotypes,不同的迁徙时间并不能防止生态型之间的杂交, Devon E. Pearse,鲑鱼的复杂表型受迁徙时间的简单变化控制, 本期文章:《科学》:Volume 370 Issue 6516 美国加州大学圣克鲁斯分校John Carlos Garza发现,这是一种简单、古老的多态性隔离在不同种群中的结果。
