Abstract

In some populations of the salamander Plethodon cinereus, two polymorphic esterase loci are in linkage disequilibrium. Short-term stability of the linkage disequilibrium is demonstrated by an age class analysis. Long, perhaps very long, term stability is suggested by its distribution. This stability and concordant geographic variation in allelic frequencies imply selective origin and maintenance. Data on the frequencies of two color morphs suggest that formation of the linkage disequilibrium is dependent on the genetic background.

摘要

在红背无肺螈的一些种群中，两个多态性酯酶基因座处于连锁不平衡状态。通过年龄组分析证明了连锁不平衡的短期稳定性。其分布表明存在长期的，也许是非常长期的稳定性。这种稳定性以及等位基因频率一致的地理变异意味着存在选择性起源和维持机制。关于两种颜色形态频率的数据表明，连锁不平衡的形成取决于遗传背景。
