Abstract
Inbreeding in wild populations can have devastating effects on fitness, but the genetic causes should not be transmitted across generations. A new study of song sparrows has revealed a parent-offspring resemblance for inbreeding, resulting from population structuring, with important implications for understanding the genetic causes of phenotypic variation in wild populations.
摘要
野生种群中的近亲繁殖会对适应性产生毁灭性影响，但遗传原因不应代代相传。一项对歌雀的新研究揭示了由于种群结构导致的近亲繁殖在亲子间的相似性，这对于理解野生种群表型变异的遗传原因具有重要意义。
