Unformatted text preview: the primary vial failed to produce crossed offspring (sepia and dumpy wing type offspring were collected in the contaminated primary vial). The F1 offspring of the female strain 2-3 and males strain 3 in the primary collection vial contained 35 bar phenotype females and 23 normal type males, the backup vial contained 21 bar phenotype females and 18 normal type males. Analysis of the obtained data sets, yielded the Bar mutation to be X-linked dominant, the dumpy wing and sepia mutations to both be autosomal recessive. Due to one cross containing only one vial, accuracy for that portion of the cross is lower than acceptable. Future studies will reduce this and other inaccuracies by collecting more parent Drosophila melanogaster , creating more crosses, increasing the number of Drosophila melanogaster tested, utilizing multiple separate collection vials and each cross population being carried out to the F2 generation....
