在人工选择下的群体中，有效群体大小可能小于实际选择的亲本数，因为在选择下的性状和选择的概率中，家系之间会有差异。表达式被开发为效应的大小，这将是更大的选择和选择的字符的遗传力越高越强烈。由于优秀个体的近亲繁殖可能会在使用后的几代中上升。
In a population under artificial selection, the effective population size may be less than the actual number of parents selected because there will be variation between families in the character under selection and consequently in the probability of selection. Expressions are developed for the magnitude of the effect, which will be greater the more intense the selection and the higher the heritability of the selected character. The inbreeding due to outstanding individuals may rise for several generations after their use.
