BIO 325 Genetics Homework 4 This homework 4 is due Thursday, Jun. 30 Please turn in your homework to your TA (NMS 3.276) or bring it to the class Please don't try to write on this sheet! Put your answers on another sheet of paper and turn that in. 1. (4 points) Following is the result from mapping for a mutation in Columbia using SSLP markers (A ~ F; differ in lengths) in a plant Arabidopsis. To do map-based cloning mutants were crossed to Ler and obtained following mutants in F2. Where is the mutation (indicate the shortest interval as between marker X and Y)? First lane is from heterozyote (as control) and the rest of them from 10 mutants at F2. (Columbia and Ler are names of ecotypes that are polymorphic throughout genome) Marker A: Columbialower bands Marker B: Columbiaupper bands Marker C: Columbialower bands Marker D: Columbiaupper bands Marker E: Columbiaupper bands Marker F: Columbiaupper bands Between Marker D & E2.
