Chromosome Essays

Compare and Contrast the Processes of Mitosis and Meiosis.

Many living organisms in the Earth can continue because of the process of producing individuals called reproduction. Both mitosis and meiosis which are nuclear division in mitotic and meiotic cell division respectively play important roles in reproduction. In this essay, the processes of mitosis and meiosis are going to be compared, and the roles and significance of these two processes in the life of flowering plants and mammals are going to be discussed. Both mitosis and meiosis involve the passing…

Drosophila_ Fruit Fly Lab

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…

Fruit Fly Experiment_ Conclusion

10. Errors and Redesign. Throughout this experiment a number of random and procedural errors were apparent; these errors could have affected the results of the experiment in a number of ways. One experimental error that occurred during the experiment was that some flies became stuck in the food source and died. The main cause of this was the fact that the fly vials were stood up (vertically) before the flies had fully recovered from the anaesthetic. This could be overcome…
