WebA raw genotype data obtained from experiments is a sequence of SNP pairs, which is also called unphased SNPs. We use a simple example to illustrate the haplotype inference prob-lem. Consider an individual A that has 00, 01, 01, 11, and 01 in five SNP locations in the genotype, where 0 represents the wild-type and 1 the mutant. WebSep 14, 2024 · Phasing is the task or process of assigning alleles (the As, Cs, Ts and Gs) to the paternal and maternal chromosomes. The term is usually applied to types of DNA that recombine, such as autosomal DNA or the X-chromosome. Phasing can help to determine whether matches are on the paternal side or the maternal side, on both sides or on … index of swarm

WebOur methods enable genotype imputation to be performed with unphased trio or unrelated reference panels, thus accounting for haplotype-phase uncertainty in the reference panel. We present a useful measure of imputation accuracy, allelic R(2), and show that this measure can be estimated accurately from posterior genotype probabilities.
