Definition of parameters used in theoretical model.

λ	The average proportion of African ancestry
pAi	The Ai allele frequency at the ith locus in the African population
pEi	The Ai allele frequency at the ith locus in the European population
λpAi	The $A_i^A$ allele frequency at the ith locus in the African-American population before selection
λ(1 – pAi)	The $a_i^A$ allele frequency at the ith locus in the African-American population before selection
(1 – λ)pEi	The $A_i^E$ allele frequency at the ith locus in the African-American population before selection
(1 – λ)(1 – pEi)	The $a_i^E$ allele frequency at the ith locus in the African-American population before selection
pmi = λpAi + (1 – λ)pEi	The Ai allele frequency at the ith locus in the African-American population before selection
