INTRODUCTION/BACKGROUND INFORMATION: In this lab we used living organisms to do genetic crosses. Our living organisms were fruit flies, and we observed and collected data from the F1 and F2 generations. Before beginning this lab we needed to understand how to do the chi-square analysis of data and the life cycle of drosophila. The drosophila eggs are small and have two filaments at one end. They are laid on the surface of the culture medium and hatch into larvae after about one day. The larvas eat almost continuously and tunnel through the culture medium while eating. The larva sheds its skin twice as it increases in size. Next in the pupal stage, a mature larva is about to become a pupa, and usually climbs up the side of the culture bottle. The last larval covering becomes harder and darker, forming the pupal case. The fruit flies have simple food requirements, occupy little space, and complete their life cycle in about twelve days.
