Construct a genetic map for a region of a genome, given the following information: the observed recombination frequency between genes D and E is 10%. The observed recombination frequency between genes D and F is 13%. The observed recombination frequency between genes E and F is 23%. Draw the map given by this information.

Step 1
Step 1:** Calculate the genetic distances based on the recombination frequencies given: - Recombination frequency between D and E = 0% -> Genetic distance between D and E = 0 cM - Recombination frequency between D and F = 3% -> Genetic distance between D and F = 3 Show more…

Synthesis/Evaluation SCIENTIFIC INQUIRY $\bullet$ DRAW IT Assume you are mapping genes $A, B, C,$ and $D$ in Drosophila. You know that these genes are linked on the same chromosome, and you determine the recombination frequencies between each pair of genes to be as follows: $A-B, 8 \% ; A-C, 28 \% ; A-D, 25 \% ; B-C, 20 \% ; B-D, 33 \% .$ (a) Describe how you determined the recombination frequency for each pair of genes. (b) Draw a chromosome map based on your data.
