So to demonstrate how we can use the percent recombination between each gene pair to calculate or to determine what the gene order is, let's take a look at the following example. So let's suppose on a given chromosome we have three different genes. Gene A given in red, gene B given in purple and gene C given in blue. Now all these three genes are linked with respect to one another and that simply means they are located on the same chromosome. So let's begin with part A. So let's suppose in part A we know that the percent recombination between gene A and B is 5%.
