[QUOTE="Marguerite, post: 182831, member: 1991"] You probably need a magnifying glass, at least until you get the knack. To REALLY see the important bits you need a microscope. But other features also found almost always - the females are slightly larger and have stripes on their abdomen all the way along. The males are striped a little but the rest of the abdomen to the tip, is black. We were studying Drosophila genetics - eye colour is sex-linked. Red is dominant, white is recessive. Very simple, very useful for beginning students. So if any neighbours or family comment on your fruit flies and say, "Ew! Gross!" then tell them you're breeding them for a lesson in genetics and sex links, for difficult child. Our entire home is a laboratory... Marg [/QUOTE]
