Assignment: Mapping the Mutation

Using the templates provided here Media:Series 2 Mapping Template.pptx, diagram the crosses that you will set up in the Mapping the Mutation part of Series 2. Highlight the progeny that will be used to continue each step of the process of determining the location of the mutation on the chromosome (linkage group) that you determined through linkage testing. Include the expected results (genotype and phenotype) for both the outcross and self-fertilization progeny used in mapping. Compose a narrative that summarizes the rational for this work as part of your overall Series 2 goals and explain how the results will allow you to determine the location of the mutated gene responsible for the abnormal phenotype you are studying.

Diagram of Crosses All possible cross outcomes diagramed accurately, completely, clearly, and concisely. One or more possible crosses missing; one or more is inaccurate, information omitted , or did not include accurate predicted ratios of progeny for genotype and phenotype. 2.5 __/2.5
Narrative description
of rational for crosses
Constructed a clear, concise, and accurate description of the rational for setting up the crosses described Rational for crosses missing, inaccurate, partially accurate; contains too much tangential information or is too simplified, is unclear 0.5 __/0.5
Narrative description
of Interpretation of Crosses
Constructed a clear, concise, and accurate description of how you will use the crosses to determine the location of the gene mutation responsible for the abnormal phenotype of interest. Interpretation of crosses missing, inaccurate, partially accurate, or unclear; contains too much tangential information or is too simplified. 2 __/2
Total 5 __/5
