White gene in the fruit fly drosophila controls eye pigment production. Flies with a normal white gene have normal pigment production which gives them red eyes. When normal white gene is moved near heterochromatin, the eyes are mottles with both red and white patches. Why is the drosophilas' eye colour red when the gene is white?
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.
