Gene interaction refers to the ways in which different genes interact with each other to produce a certain trait or phenotype. This field of research focuses on understanding how genes work together in complex networks to influence various biological processes, such as development, disease susceptibility, and evolution. The study of gene interaction involves analyzing the effects of multiple genes on a particular trait, as well as the interactions between genes and environmental factors. Researchers use various experimental techniques, such as genetic mapping, gene expression analysis, and computational modeling, to investigate the relationships between genes and their interactions. Gene interaction research is important for advancing our understanding of genetic regulation and developing new strategies for treating genetic diseases.
