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%. The percent recombination between B and C is 3% and that between A and C is 8%. So knowing what the percent recombination is between each gene pair, let's now determine what the order of the genes is. So let's suppose we have a chromosome.
