Genetic Recombination and Gene Mapping Practice Problems

1. Bozeman video example:

Where are the genes?

2. BOZEMAN video question:

Where are the genes?

3. The following crossover frequencies were noted via experimentation for a set of five genes on a single chromosome: Create a gene map using the information.

a. A and B—35% b. B and C—15%c. A and C—20%d. A and D—10%

e. D and B—25%f. A and E—5%g. B and E—40%

4. Four genes, J, K, L, and M reside on the same chromosome. Given that the crossover frequency between K and J is 3, between K and L is 8, between J and M is 12, and between L and M is 7, what is the order of the genes on the chromosome?
