Abstract
New mutations provide the source of all genetic variation but their impact on trait variation remains poorly understood. A new study published in PLOS Biology addresses this question, finding that new mutations exert only weak effects on some traits in mice.
摘要
新突变提供了所有遗传变异的来源，但它们对性状变异的影响仍知之甚少。发表在《PLOS Biology》杂志上的一项新研究解决了这个问题，该研究发现，新突变对老鼠的一些特征只产生微弱的影响。
