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. So let's suppose the chromosome is this chromosome right over here. Okay? So the question is if we know what the percent recombination is, how can we use that information to actually determine what the order of the genes is?
