The Hardy-Weinberg Law has these 5 conditions: -There must be no mutations. -There must be no arriving (immigration) or leaving (emigration) of individuals to and from the population. -The population must be large. -All individuals must have the same chance of surviving. -The matings of individuals organisms must be random; no meetings can have preferences.
So, in this case, your best choice would be *C, the populations must be infinitely large*
