What's wrong with this one?

This is a plot is of ratio of female : male recombination rate. Because ratios below one are sandwiched between one and zero, much greater emphasis is given to ratios above one, when the female recombination rate is greater than the male recombination rate.

What should have been done?

This should have been done on the log scale (preferably log base 2), so that ratios above and below one are given equal emphasis.
