摘要
This paper describes a non-iterative, recursive method to compute the likelihood for a pedigree without loops, and hence an efficient way to compute genotype probabilities for every member of the pedigree. The method can be used with multiple mates and large sib-ships. Scaling is used in calculations to avoid numerical problems in working with large pedigrees.
