This article provides an in-depth analysis of the mechanisms of interaction between non-allelic genes in di- and polyhybrid crosses. In genetics, the interaction of not only allelic but also non-allelic genes plays an important role in the formation of hereditary traits. The study highlights the biological essence of such genetic phenomena as complementarity, epistasis, and polymery, their types, and significance in breeding. The complex interrelationships between genes through di- and polyhybrid crossing methods, as well as the causes and results of the formation of new genotypic combinations, are also illustrated with examples. The article systematically analyzes the factors influencing the phenotypic expression of genes based on data obtained using modern genetic analysis methods. This research is of theoretical and practical importance in the fields of genetic selection, biotechnology, and hereditary variability management.
