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.

![Below is a diagram of a gene that is not normally alternatively spliced. All four exons (represented as boxes) are found in the mature mRNA. Transcription starts at the arrow
labeled TSS, transcription stops at the line labeled TT, and the promoter location is indicated by the line. The indicated DNA sequences for two individuals are found within
exon 2 as indicated, with Individual 2 having a mutation. Both sequences are in-frame with the upstream start codon.
