Circumstances assuring a unique stable equilibrium are investigated for a subdivided population with several alleles segregating at a single locus. For a broad class of selection regimes entailing heterozygote viabilities greater than the geometric mean of the corresponding homozygote viabilities, a stable fixation state precludes any other stable equilibria if either total-panmixia or temporal variation is operating. This extends known results for two alleles at a single locus and partially delimits when some of the bizarre behaviour engendered by multiple alleles may occur.
对于在单个基因座上有多个等位基因分离的细分群体，研究了确保唯一稳定平衡的情况。对于一类广泛的选择机制，即杂合子活力大于相应纯合子活力的几何平均值，如果存在完全随机交配或时间变化，则稳定的固定状态排除了任何其他稳定平衡。这扩展了单个基因座上两个等位基因的已知结果，并部分界定了多个等位基因可能产生的一些奇异行为出现的条件。
