Any nuclear mutation or cytogeneic change that effects the genotype 
may well qualify the new "offspring" as a sport, but what about 
transposible elements?  If a transposible element moves from one 
location to another location and results in a sport via a "position 
effect", does that really change the genetic makeup of the plant?
