Actually you still have to type it that way, because DYS413 is
downstream from J2a. There are some J2a chromosomes that are
DYS413>18. So, J2-(DYS413<=18)(xJ2a,J2f) gives the maximum
information.

People with a short DYS413 can be sure to be in clade J2a. People with
a long one that are negative for J2b (old J2e, or M12) can also be
very certain that they are in J2a.

The authors promise a supplement which defines the new J2 phylogenetic
changes in detail. I will blog about this once it becomes available.
