A stabilizing selection which is made in cattle according to phenotypic characters affects simultaneously a genetic character--the level of individual heterozygosity++. As a result animals with mean (modal) level of heterozygosity++ have the least probability of elimination. Similarly, the driving selection in pigs and horses leads to a change in both phenotypic characters and genetic character, the level of individual heterozygosity++. In this case the most heterozygous animals have the least probability of elimination.
根据表型特征在牛中进行的稳定选择会同时影响一个遗传特征——个体杂合度++的水平。因此，具有平均（众数）杂合度++水平的动物被淘汰的概率最低。同样，猪和马中的定向选择会导致表型特征和遗传特征（个体杂合度++的水平）都发生变化。在这种情况下，杂合度最高的动物被淘汰的概率最低。
