Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
The discovery of DNA as genetic material is one of the most significant discoveries in molecular biology. More DNA research and a better grasp of its chemical properties have taught us more about inheritance, genetic codes, and other topics. Previously, proteins were thought to be the bearers of inheritance, but the discovery of DNA has allowed us to understand how DNA codes for proteins. To code the information, it goes through three stages: replication, transcription, and translation.
