Imputation in genetics refers to the statistical inference of unobserved genotypes. It is achieved by using known haplotypes in a population, for instance from the HapMap or the 1000 Genomes Project in humans, thereby allowing to test for association between a trait of interest (e.g. a disease) and … Zobacz więcej In genetic epidemiology and quantitative genetics, researchers aim at identifying genomic locations where variation between individuals is associated with variation in traits of interest between individuals. Such studies hence … Zobacz więcej Designing accurate statistical models for genotype imputation is very much related to the problem of haplotype estimation ("phasing") … Zobacz więcej • List of haplotype estimation and genotype imputation software • Haplotype estimation Zobacz więcej Genotyping arrays used for genome-wide association studies (GWAS) are based on tagging SNPs and therefore do not directly genotype all variation in the genome.
