Modeling multiple interactions between multiple loci

A computer implemented method for generating a quantitative model of genetic effect, the computer implemented method comprising:

• receiving, by a processor, a set of loci of an entity, wherein each locus in the set of loci is associated with a contribution value to a given physical trait;
• identifying, from the set of loci, a first set of interacting loci associated with a first interaction and at least a second set of interacting loci associated with at least a second interaction, wherein the first interaction is associated with a first interaction model, and wherein the at least the second interaction is associated at least a second interaction model;
• generating a model of a quantitative value of the entity based on at least
• the contribution value associated with each locus in the set of loci,
• a contribution value of the first interaction as defined by the first interaction model, and
• a contribution value of the at least the second interaction as defined by the at least the second interaction model.
