 Enter 37-mkr FTDNA haplotype & generations, then click GO to see the evolution of a single line for x generations.
Each marker is allowed to evolve at the Chandler rate for x generations.  All mutations are single step with an equal up/down probability.
389ii is converted to 389b before evolution, then reconverted to 389ii.  Multiple markers are not monotonically reordered after evolution.
A maximum of 999 generations in permitted, but the routine runs slow with >100 generations.
