Natural populations can evolve at some loci while being in Hardy-Weinberg equilibrium at other loci. Some populations evolve slowly enough that evolution cannot be detected 16
Hardy-Weinberg Genetic Equilibrium Hardy-Weinberg equilibrium describes populations that are not evolving Genotype frequencies stay the same over time as long as certain conditions are met: Very large populations No emigration or immigration No mutations Random mating No natural selection...

In order for a population to be in HW equilibrium, 5 conditions must be met: 1. Very large population 2. No migration 3. No net mutations 4. Random mating 5. No natural selection Therefore, … We do not really expect a natural population to be in Hardy Weinberg equilibrium ...

Hardy–Weinberg equilibrium,叫做哈迪-温伯格平衡。该定律 提出,对于一个足够大的群体,在群体中各个个体之间随机交配,在 没有突变,个体迁移,遗传漂变等因素发生的情况下,这个种群的基 因频率和基因型频率可以一代代稳定不变,保持平衡。 对于二倍体生物而言,等位基因 A 的频率用 p 表示,a 的频率用 q 表示,在满...
