A computer simulation model for mass selection in a random mating autotetraploid population was presented. Selection was based on a single quantitative trait controlled genetically by 40 genes, 4 on each of 10 chromosomes. The model allowed for arbitrary gene frequency, double reduction, linkage, dominance, epistatic deviations involving two loci, population size, intensity of selection, and environmental variance. Effects of mutation, migration, and natural selection were ignored. Preliminary results revealed that linkage affected selection response in diploid and autotetraploid populations about equally when genetic variance was primarily additive. With dominance, linkage had a greater effect on diploids.
