Well, what's for certain is that two hybrids can't have offspring.
Perun said:The DNA of human beings and chimpanzees are identical by 98%. I would say it is very likely that a human can fertilise a chimp and vice versa, it has only never been tried.
One fact that you missed is that hybrids are always sterile. A mule can not have children. A human-chimp hybrid could not have children as well.
