Chimps have one more chromosome than humans. The fusion event occurred before neanderthals arose (sorry Mr. Sawyer).
It's interesting to ask how interfertile neanderthals and humans were. As I understand it, the genetic evidence seems to show selection against some swaths of the neanderthal genome, possibly indicating fertility problems when crossing with H. sapiens.
As for human/ape hybrids. This reminds me of an old joke.
A scientist puts an want ad in the paper (this is an old joke, remember): "Man wanted for human/ape crossbreeding experiment. $5,000."
He soon gets a call from a subject. "I'll participate in your experiment on two conditions."
"First, my identity must forever be kept entirely secret."
"And second... can I pay the $5,000 in installments?"
