Now let's move on to gene B. Now we know that the percent recombination between gene A and gene B is 5%. Now recall in our discussion of gene mapping we said that one map unit or one recombination unit is equal to 1% recombination. And what that means is because we have a 5% recombination between A and B, the distance between A and B is equal to five map units or five recombination units. Now we can place the gene B either above or below because that doesn't really matter. Let's put it below.
