How would that work? The chimp swaps it’s mother and father’s DNA at its ‘hot spots’ and the human swaps it’s mother and father’s DNA at its ‘hot spots’.
The fact that the hot spots were different would have zero effect on the viability of the combined gametes in the hybrid.
It would only cause problems once a viable hybrid attempted to produce gametes - and it’s mother and father’s DNA didn’t match up.
This is the reason why mules are (mostly) sterile - because its mother (horse) and father (donkey) DNA will not usually match up well enough to produce viable gametes. This makes a mule (mostly) infertile - but it doesn’t stop the mule itself from being viable.
So I ask, how would THAT work?
The "species barrier" begins at that point rather than with some other process like different shaped sex organs (common in insects and readily created by infection with a bacteria ~ the name of which escapes me at the moment - I think it's a genus name ~ Wolbachia, but there are others that also affect insect sex organs)
