Fruit fly (Drosophila melanogaster). Animated coloured scanning electron micrograph (SEM). Fruit flies have only four pairs of chromosomes and many visible traits that can be seen with low magnification, which makes them good test subjects for studies in genetics. Other factors that make them good test subjects are their ability to produce large numbers of offspring and that they are easy to move around and examine.
