Abstract
The effects on a panmictic population of a patchy environment and stochastic selection were investigated by computer simulation. The model allowed for different patterns and intensities of selection and various densities of distribution of the offspring. It delineated the effects of these variables on the correlation between the genotype and the environment, the level of heterozygosity, the change in gene frequency from generation to generation and the divergence between similar populations due to random effects.
摘要
通过计算机模拟研究了斑块状环境和随机选择对随机交配种群的影响。该模型考虑了不同的选择模式和强度以及后代的各种分布密度。它描述了这些变量对基因型与环境之间的相关性、杂合度水平、基因频率代代变化以及相似种群由于随机效应而产生的差异的影响。
