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 thread-like structure that consists of the genetic information of the organism, located within the nucleus of the cell is called chromosome. The DNA (deoxyribonucleic acid) is the hereditary unit of an organism that consists of the chromosome. During the process of cell division the chromosome forms duplicate copies of itself, which are inherited by the daughter cells.
