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?
