How this affects the population depends on the assumptions that are violated. Assortive mating is a deviation from Hardy- Wienberg principle assumption: mating is random as it is a form of non random mating. 13. flower shops in hershey paWebTwo other important exceptions are inbreeding (mating with relatives) and enforced outbreeding. Both can shift the equilibrium proportions expected under Hardy-Weinberg calculations.
