The transition probabilities between ancestry pairs.

If Ak represent a specific ancestry and θk represents the admixture proportion of that ancestry in the admixed population, then these equations are the transition probabilities for all possible types of transitions given a probability rj of one or more recombinations occurring between the previous informative CSV and the jth informative CSV. The rows represent the ancestry state at the previous CSV and the columns the ancestry state being transitioned into at the jth CSV.

若$A_k$代表某一祖先起源成分（ancestry），$ heta_k$代表该祖先成分在混合人群（admixed population）中的混合比例（admixture proportion），那么下述方程即为所有可能转换类型的转移概率（transition probabilities），其前提是在前一次有信息的CSV（informative CSV）与第j次有信息的CSV之间，发生一次或多次重组（recombination）的概率为$r_j$。其中，矩阵的行对应前一次CSV处的祖先状态，列对应在第j次CSV处转换至的祖先状态。
