Are we all compatible ?..ie: can one human from any lineage on the planet procreate with any other human ?..or are their proven  procreational difficulties in certain lineages ?

Are there predispositions  for a more voracious fertility demonstrated in some lineages more than others ?

Conversely is there an opposite to the above ?

There are certainly problems with incompatible rhesus blood factors.

Bout this can occur within a lineage AND only means the progeny will not be carried tot term or not live if born.

The answer is Yes.

The sailors of the Age of Discovery have proven this to be true.

All the sailors proved was that their is no geographic boundary where humans on one continent cannot breed with humans on another continent.

The question referred to lineage, which can be defined as anybody with an inheritable trait that can trace that trait through their ancestry - it need not be geographically bound.

Define human.
If we are talking about humanity as a species then, by at least one fairly popular definition, all members of that species can interbreed.
If you can't interbreed with other humand then it's probably best to reguard it as a genetic fault.
Incidentally, weren't Rhesus factors named because they also occur in Rhesus monkeys? If so doesn'yt that mean they are just an oddity of biology (perhaps mammal or primate biology), rather than anything to do with humans.
