AlphaFamImpute: high-accuracy imputation in full-sib families from genotype-by-sequencing data

Abstract: Summary AlphaFamImpute is an imputation package for calling, phasing, and imputing genome-wide genotypes in outbred full-sib families from single nucleotide polymorphism (SNP) array and genotype-by-sequencing (GBS) data. GBS data is increasingly being used to genotype individuals, especially when SNP arrays do not exist for a population of interest. Low-coverage GBS produces data with a large number of missing or incorrect naïve genotype calls, which can be improved by identifying shared hapl… Show more

“…, Beagle ( Browning and Browning 2009 ) or AlphaPeel ( Whalen et al 2018 ). With the use of offspring-parent information such as AlphaFamImpute ( Whalen et al 2020 ) or FImpute ( Sargolzaei et al 2014 ), the imputation likely increased accuracy of G and H matrices used in GBLUP and single-step methods ( i.e. , ssGBLUP) ( Hickey et al 2012 ).…”

“…Parental genotypes from one dataset were substituted when a sample by the same name was found to be inconsistent in another. Genotypes were phased and imputed using AlphaFamImpute 69 v0.1 and parent-averaged linkage maps ( Supplementary Data 3 ) constructed in JoinMap 70,71 v4.1 with the maximum-likelihood mapping function for cross-pollinated populations, which were then integrated into a composite map using LPmerge 72 v1.7. Further detail regarding genetic linkage mapping can be found in Supplementary Note 2 .…”

“…The high-density individuals can then be used as a reference to impute the low-density individuals to high-density (Gorjanc, Battagin, et al, 2017; Gorjanc, Dumasy, et al, 2017; Jacobson et al, 2015; Thorn et al, 2021). Many imputation methods for plant and animal breeding have been developed over the years such as Fimpute (Sargolzaei et al, 2014), AlphaPlantImpute (Gonen et al, 2018), AlphaFamImpute (Whalen et al, 2020), AlphaImpute2 (Whalen & Hickey, 2020), OutcrossSeq (Chen et al, 2021), AlphaPlantImpute2 (Thorn et al, 2021), HBImpute (Pook et al, 2021). The majority of these methods are designed for genotyping only a fraction of the population at high-density.…”
