Now to answer that question, we actually have to look at the recombination percent, or the percent recombination between the final pair A and C. So the percent recombination between A and C must be 8%. And notice if we place C above B. So three units above B, that means it's going to lie somewhere here. And so because this total distance is five map units, placing it above B means the distance between A and C would be only two map units because five minus three is two. And so what that implies is C. The gene C must be placed below B. And that will work out because as we place it right over here, so this is our gene C. We know that the distance is 3%, so three map units.
