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.
Discuss mutations outside the coding sequence that
could affect gene expression
A mutation is defined as any change in sequence of the DNA molecule due to any biological or chemical agent known as mutagen. A DNA molecule is more prone to such errors during replication. Any change in the sequence of the DNA, most of the times, alters the downstream expression of a gene.
