A probability model for the formation of genotypes from two alleles is given and expressed in terms of two parameters, α and β; α ≈ β corresponding to equilibrium. The likelihood for (α, β) given genotype daa is found providing estimation of α. A Bayesian test of the hypotheses that α ≈ 0 is also considered. The choice of prior distribution is discussed. Comparison is made with the usual tests of equilibrium proposed. An advantage of this approach is the provision, in α, of a measure of departure from equilibrium. There is a discussion of the general Bayesian procedure of investi
