While humans and chimpanzees have similar/identical sequences on many
chromosomes, they have different *numbers* of chromosomes (humans have
less -- somewhere after diverging, some of ours merged). A human/chimp
crossbreed would have unpaired chromosomes. That's *bad*. An embryo
probably wouldn't carry to term, and even if it did, there would
probably be massive defects. Defects caused by unpaired chromosomes
(in humans) often include mental retardation. (I'm not sure if that's
retardation by human terms, or by chimp terms, but I wouldn't bet money
on getting a good conversationalist.)

No research that I know of, but I must point out that such reserach is
one of anthropology's odder urban legends. Physical anthropologists have
told me they've heard rumors about "Russian" and/or "Chinese" scientists
cross-breeding humans and chimps, but it's all just Cold War Commie-bashing
folklore.
