BIO 201 Class Project - Mapping e(r) Transgenes on the X Chromosome of the Fruit Fly, Drosophila melanogaster

One goal of the Tsubota lab is to create chromosomes that have multiple copies of the e(r) gene. Previously, genetic transformation was performed to insert extra copies of the e(r) gene into the X chromosome of the fruit fly, Drosophila melanogaster. The positions of these extra copies can be determined by genetic recombination experiments. In these experiments, large numbers of fruit flies need to be examined to obtain accurate map distances and positions. To obtain the necessary numbers, the entire class of BIO 201 Biology I Fall 2011 was recruited to perform the study. Five different e(r) transgenes were mapped as part of a recombination lab. The class examined 6493 flies in mapping the five transgenes. One of the transgenes mapped close to the tip of the X chromosome. The other four transgenes mapped closer to the base of the X chromosome. The data collection and analysis will be discussed.
