BISC219/F12: Assignment Series2 Linkage Testing Crosses
Lab 3 Assignment: Linkage Analysis
At or before the beginning of the next lab, using the templates provided here Media:Series 2 Template for linkage and mapping CrossesF11.ppt, construct a diagram of crosses that you will set up in the Linkage Testing part of Series 2. In the template, make sure to highlight the progeny that will be used to continue each step of the process of linkage testing. Include the expected results (genotype and phenotype) for both the outcross and self-fertilization progeny. Compose a narrative description that summarizes the rational for Linkage Testing as an important part of your overall Series 2 goals. Explain what you are looking for in the results of these crosses that will allow you to determine the linkage group to which your mutated gene of interest belongs.

Lab 3 Assignment: Linkage Analysis
| At or Above Standard | Below Standard | Possible Points |
Points
Earned | |
|---|---|---|---|---|
| Diagram of Crosses | All possible cross outcomes diagrammed 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 linkage group to which your mutated gene belongs. | Interpretation of crosses missing, inaccurate, partially accurate, or unclear; contains too much tangential information or is too simplified. | 2 | __/2 |
| Total | 5 | __/5 |
