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.

Transcription is the process cells use to copy information from DNA into messenger RNA copies. Part of the chromosome's tightly wound-up long strand of DNA is "loosened" to allow for RNA polymerase room to copy part of the DNA. Think of this as opening a page out of a giant book with thousands of pages to make a copy of just that one page. One side of the DNA strand is the template strand (or anti-sense strand) and is used by an enzyme called RNA Polymerase to create the messenger RNA. RNA Polymerase is directed by a bunch of proteins called transcription factors to the spot it needs to start copying. RNA Polymerase reads the template strand from the 3' end to the 5' end and creates a messenger RNA strand that is complementary to the template strand.
