Tweaking a single gene alters the courtship behaviour of fruit flies, a new Austrian study shows. By altering a gene called 'fruitless' (fru), the researchers, based at the Institute of Molecular Biotechnology in Vienna, bred female flies that courted other females. But altering the same gene in male flies produced... [Read More]
