Whether this is caused by a different version of the same gene, or by a distinct driver that arose independently on S. pombe chromosome 3, will be a very interesting follow-up question.
Although these drivers likely arose independently under a more typical scenario for spread of meiotic drivers, their joint action is what leads to the near complete sterility in the Sp/Sk hybrids.
