Drosophila have been used for genetic research for more than 50 years because they breed rapidly. Not only do they share 75 per cent of the genes that cause disease in humans but their large chromosomes have barcode-like stripes so changes to the genetic code can be easiy identified under a microscope.
In the garden they can be used as an indicator for potential
