Panmixia

Panmixia is random mating within a breeding population, without systematic choice by genotype or phenotype. In a homogeneous genetic model it makes the two parental gamete draws independent, yielding the Hardy-Weinberg equilibrium genotype probabilities $p_i^2$ and $2p_i{p}_j$. It is a modelling assumption; assortative mating and population stratification are distinct ways a population can depart from it.
