The genetic difference between man and chimpanzeese (depending on the source) is roughly 1 to 1.2 chromosomes (chimpanzee chromosome 19 and 22 and the human chromosome 17)
I think the reason he called this definition -2genes was due to the fact that not all humans are created equally. In some mentally / emotionally deficient case studies, it would appear that in a select group of genetic human failures GHF the normal process of evolution was bipassed in order to preserve the more primative traits of the subspecies. Due to these circumstances, the author of this definition excercised "observational liberties" based on real life experiences and not a controlled biogenetic analysis.

An inbred sheep dickin', illiterate / hillbilly-d poppin', white trash (or not) southern racist with a heroin or opiate addiction. Known for fathering several younger brothers (Leroy, Luke and Levi), and a sister named May (aka mama) in an effort to boost the working population for the family's All Natural Fertilizer business. A cracker so dumb, they stole Oxytocin instead of Oxycontin from the drug store cause they couldn't spell. A cracker so dumb, they still use manure as the "secret ingredient" for binding the Sowbelly n' Tuna Croquettes.
Luke: How many times do I have to ask you May, to sleep in my bed and keep me warm. Don't make me insist on it now.
May: You're not the only one in this family with problems.
Luke: When my brother, I mean my daddy is dead and buried, I'll be the next one in line to be gettin' with you regular like.
May: That's fine thinking Luke! You mean to tell me, "when that smack cracker brother father of our's dies for the hell he has caused this family's gene pool", you gonna be my daddy too?
Luke: Who said anything about gettin' a pool!
