And the distance between this point right over here, let's say the center of gene A and the center of gene B is given to us to be five map units. Okay? And the reason we know it's five map units is because 1% recombination. So remember, 1% recombination is equal to one map unit. And because we have 5% recombination that is equal to five map units. Now let's move on to the second pair.
