Tiny changes in gene expression can lead to big differences in eye size of fruit flies

An international team of scientists has discovered that tiny changes in the timing of the expression of a single gene can lead to big differences in eye size. Gene expression is the process by which the information encoded in a gene is turned into a functional output, for example, the production of a protein.
