Home Â» Polygenic inheritance. Definition. noun. A non-Mendelian form of inheritance in which a particular trait is produced by the interaction of many genes. Supplement.
Abstract. Monogenic inheritance refers to genetic control of a phenotype or trait by a single gene. For a monogenic trait, mutations in one (dominant) or both (recessive) copies of the gene are sufficient for the trait to be expressed.igenic inheritance refers to mutation on two genes interacting to cause a genetic phenotype or disease. Triallelic inheritance is a special case of digenic inheritance that requires homozygous mutations at one locus and heterozygous mutations at a second locus to express a phenotype.
