Some of the assumptions of the multifactorial hypothesis are as follows:
1. Several numbers of loci are involved in the manifestation of a particular trait.
2. Any given loci have no dominant/recessive relationship.
3. Some particular loci can work in an additive manner, adding or detracting from the overall phenotype.
4. Environmental factors combine with genotypes and play a major role in specifying the final phenotype.
