In other words, there is no evolu tionary force acting on the population What are the assumption of HWE? ✔✔ No Selection, No Gene flow, Random mating, Infinite population size, No mutation Is it really possible for a population to be in HWE? ✔✔ no Why is Hardy -Weinberg used in populatio n genetics? ✔✔ It is used as a null model, or, in other words, as a point of comparison. By comparing real populations to HW, we can determine if they are evolving (and generally, at what rate)
