Abstract
Budding yeast provides a useful resource for studies of gene function. A new analysis of the fitness effects of deletion mutations in budding yeast reveals that genes that have duplicates create lower fitness losses when inactivated than do genes that are singletons.
摘要
芽殖酵母为基因功能研究提供了有用的资源。一项对芽殖酵母中缺失突变的适应性影响的新分析表明，具有重复基因的基因在失活时产生的适应性损失比单拷贝基因要小。
