I guess there's still some debate about how much of its genetic material originated from which teosinte subspecies, but given that the two happily interbreed and as well as comparisons of genetic sequences that question has been settled, although you're absolutely right the wild ancestor of corn was a big question mark for a long time.    From Wordnik.com.  [ScienceBlogs Channel : Life Science] Reference
