Inbreeding and runs of homozygosity before and after genomic selection in North American Holstein cattle

BMC Genomics
PMCID: 5787230
PMID: 29374456
DOI: 10.1186/s12864-018-4453-z

[…] A base population consisted of 500 females and 50 males was simulated using QMSim []. Sixty overlapping generations were generated by mating 50 sires at random to 500 dams. Each dam produced two progeny in each generation. Sire and dam replacement rates were 0.5 and 0.3, resp […]


Incorporation of causative quantitative trait nucleotides in single step GBLUP

PMCID: 5530494
PMID: 28747171
DOI: 10.1186/s12711-017-0335-0

[…] Using the software QMSim [], we simulated a livestock population under selection for a single quantitative trait that has a heritability of 0.3. A historical population was generated by mutation and drift over 1000 gene […]


Performance Gains in Genome Wide Association Studies for Longitudinal Traits via Modeling Time varied effects

Sci Rep
PMCID: 5428860
PMID: 28377602
DOI: 10.1038/s41598-017-00638-2

[…] ioned. We evaluated statistical power, type-I error rate as well as the accuracy of SNP effect estimated for each GWAS method through 1,000 replication.Population and genomic data were simulated with QMSim software. The simulation started with a base population of 50 males and 50 females in generation −1,000, followed by 1,000 discrete historical generations (generation −1,000 to −1) with the same […]


Metafounders are related to Fst fixation indices and reduce bias in single step genomic evaluations

PMCID: 5439149
PMID: 28283016
DOI: 10.1186/s12711-017-0309-2

[…] To assess the quality of genomic predictions using one metafounder, we simulated data using QMSim []. The simulation closely followed that in [] to mimic a dairy cattle selection scheme scenario. A historical population undergoing mutation and drift was generated, followed by a recent popula […]


Systematic genotyping of groups of cows to improve genomic estimated breeding values of selection candidates

PMCID: 5039940
PMID: 27677439
DOI: 10.1186/s12711-016-0250-9

[…] QMSim first simulated a so-called historical population, which consisted of 2000 unrelated animals with a balanced sex ratio. These animals were randomly mated for 2500 generations. To create a suffic […]


Evaluation of breeding strategies for polledness in dairy cattle using a newly developed simulation framework for quantitative and Mendelian traits

PMCID: 4926303
PMID: 27357942
DOI: 10.1186/s12711-016-0228-7

[…] and stochastic simulation techniques require genetic (co)variance components for both traits. Regarding the situation with polledness, only assumptions can be made since results are not available yet.QMSim [] is a powerful whole-genome stochastic simulation program that was designed to simulate a wide range of genetic and genomic architectures and population structures, particularly in livestock. […]
