Population Cage Objectives: The purpose of this experiment is to emulate evolution and natural selection over a short period of time in a sample population of Drosophila. Also, to learn to identify and count gene frequencies within the sample population and to compare those frequencies between population cages that begin with different frequencies. Variables: Independent Variables: Initial gene frequencies within population cage Number of flies used Dependent Variables: Final gene frequencies within population cage Differences in gene frequencies between population cages Hypotheses: H 0 : The gene frequencies of the sample population will not level off and become consistent. H 1 : The gene frequency of the Bar with eventually become stable and consistent. Conclusion: I reject the null hypothesis. Intro:

In this experiment we are emulating natural selection and evolution within a sample population by using two genes, wild and Bar, in Drosophila. The Bar gene, which is a mutation, expresses itself in
