1.To know if a population is in Hardy-Weinberg Equilibrium scientists have to observe at least two generations. If the allele frequencies are the same for both generations then the population is in Hardy-Weinberg Equilibrium. Example 1b: Recall: the previous generation had allele frequencies of ���� = 0.6 and ���� = 0.4.
