<p><italic>SNPscan breeder</italic> is a software that enables the simulation of breeding programs using simulated individual whole genome data, different genetic architectures of a trait of interest, different mating designs and different selection criteria, i.e. pheno-types, breeding values from progeny tests, marker-assisted selection (MAS) and genomic selection (GS). The impact of breeding population size, mating design, selection intensity, genetic architecture, heritability and selection criteria on genetic gains, kinship, inbreeding and genetic diversity can be evaluated to optimize the breeding program.
