Quizplus · Accepted Answer

The additive model of genetic analysis of complex traits assumes that each gene involved has an equal effect on the phenotype. This means that the effect of each allele is equal regardless of the presence or absence of other alleles. This is in contrast to the cumulative or epistatic models, which take into account the interactions between different alleles, or the polygenic model, which assumes that multiple genes contribute to the phenotype with different effect sizes.
