Crossing over of Chromosomes “meiosis” ONLY takes place in reproductive cells.

The failure of meiosis to occur means sterility not non-viability.

Meiosis is not necessary to create a viable embryo - only to create a viable gamete - and both chimps and humans are able to create viable gametes.

The inability to reproduce may be due to any number of genetic factors - but meiosis hot spots ARE NOT ONE OF THEM.

If you have an actual source that says different - please provide it.

However your inability to explain how it would work (and your inability to provide a source that would explain it) makes it likely that you were just confused about the subject.

Failure of meiosis causes sterility, not non-viability.

Horses and men are both able to produce viable gametes. That doesn't mean you can cross breed them to get a viable embryo.

Obviously that could be interpreted as sterility ~ NO VIABLE EMBRYO ~ which is, of course, just that.

You can also have Viable Embryos that themselves are unable to produce useful gametes.

I think you slipped a cog here.

Or, you and I may be reading the same scientific language version of the same material differently. To dispel doubts here's a POP SCIENCE version: http://www.sciencenews.org/view/generic/id/339172/title/Geneticists_go_ape_for_better_primate_family_tree
