The history of fruit flies is considered a tradition. Research of these flies initially entered labs 100 years ago. Thomas Hunt Morgan‚ who lived from 1866 to 1945‚ was the founder of drosophila genetics. Thomas preformed his research in Morgan lab at the Columbia University in 1910. Here was when they found a famous mutation‚ know as the white-eyed fly. Quite an accomplishment was this discovery‚ but the end of the 1980’s there were 3‚000+-recorded mutations. Now drosophila is very popular; so popular

OF FRUIT JUICE Aim: To investigate the vitamin C content of fruit juice.Hypothesis: I believe the more drops of fruit juice taken to decolourise DCPIP‚ the smaller the amount of vitamin C in that fruit juice. This is because DCPIP needed to be decolourised by ascorbic acid in fruit juice‚ so less concentration of ascorbic acids means that more ascorbic acids is needed to decolourised DCPIP. I believe that freshly squeezed orange is going to have the most Vitamin C content because the fruit itself
