Approach: Results: - see report booklet Discussion/Conclusions: Part III A: Examining Asci Part III B: Determining Map Distance Part IV Atypical Segregation Ratios Responses to Review Questions: 3) Yes we did. a. This is derived from a chromatid that possessed a hybrid DNA molecule. b. This pattern results from a complete chromatid change....
