WebPhasing is the process of inferring haplotypes from genotype data. Efficient algorithms and associated software for accurate phasing in pedigrees are needed, especially for … WebNov 23, 2024 · The degree of variability introduced by genotype imputation differs across algorithms, where pre-phasing algorithms with stochastic elements introduce the greatest degree of score variability. In most cases, PRS variability due to imputation is minor (< 5 percentile rank change) and does not influence the interpretation of the score.

In genetics, haplotype estimation (also known as "phasing") refers to the process of statistical estimation of haplotypes from genotype data. The most common situation arises when genotypes are collected at a set of polymorphic sites from a group of individuals. For example in human genetics, genome … See more Genotypes measure the unordered combination of alleles at each site, whereas haplotypes are the two sequences of alleles that have been inherited together from the individual's parents. When … See more Many statistical methods have been proposed for estimation of haplotypes.
