Abstract
A frequency-dependent selection model proposed by Huang, Singh and Kojima (1971) was found to be more effective at maintaining genetic variation in a finite population than the overdominant model. The fourth moment parameter of the distribution of unfixed states showed that there was a more platykurtic distribution for the frequency-dependent model. This agreed well with the expected gene frequency change found for an infinite population.
摘要
黄、辛格和小岛（1971年）提出的频率依赖选择模型被发现，在维持有限种群的遗传变异方面比超显性模型更有效。未固定状态分布的四阶矩参数表明，频率依赖模型的分布更呈低峰态。这与无限种群中预期的基因频率变化非常吻合。
