Annotation: The article aims to determine the level of accuracy of the expected theoretical result in the process of processing or creating problems related to the inheritance of nonallel genes (complementary, polymer, epistasis) using a statistical method. Inheritance of non-allelic genes was analyzed statistically using complement, polymer, epistasis, gene inheritance in F2 and character separation using the x2 method.

Keywords: Polymer, epistasis, complementary, inhibitor, epistatic, hypostatic, cumulative, nocumulative, statistical method, x2 method, fisher table, phenotype, genotype, dominant, heterozygous, recessive.
