Maybe. I don't doubt the possibility Oda remembers his basic biology lessons. One fun thing to remember about genetics: there are always exceptions. For example, the conqueror's haki thing could just be a compleeeetely random mutation that like happens alot in a certain population (doesnt even have to be a lineage factor). We've also never seen a female with conqueror's haki, which might be relevant (though I doubt it's male-only). So I just wanna say that every genetic process is still possible with this, not just the Mendelian system you described.
