1. A system for performing trio-based phasing, comprising: one or more processors configured to: obtain a set of preliminary phased haplotype data of an individual; establish a dynamic Bayesian network based at least in part on the set of preliminary phased haplotype data of the individual and phased haplotype data of at least one parent of the individual; and determine, based on the dynamic Bayesian network, a set of refined haplotype data of the individual; and one or more memories coupled with the one or more processors, configured to provide the one or more processors with instructions.
