Determining Gene Order
Part of the gene mapping process involves determining what the order of genes is along a given chromosome. So how do we determine the gene order? Well it turns out that if we know what the percent recombination is between any pair of genes on the particular chromosome, we can determine what the gene order is. Suppose we have three genes - A, B and C - which are linked with respect to one another (found on the same chromosome). What is the gene order if (a) the percent recombination between A and B is 5%, that between B and C is 3% and that between A and C is 8% (b) the percent recombination between A and B is 5%, that between B and C is 3% and that between A and C is 2%. The answer can be found in the lecture itself.
