What are the inevitable ways that Jews will try to escape persecution as populations wake up to redpills?

Let's say goyim become dominant again and subjugate Jews. Gene tests would be an important way to out them. But genetic engineering will probably become eventually affordable and widespread, so Jews will be able to temporarily mask their genetic makeup, before inserting them in again. But this also means they can delete their Jewish genes and simply abandon that identity. And a large fraction of them would under pressure, as a third of Muslims birthed in the West abandon Islam. This calls into question what even makes up Jewish identity, and since there are non-Jewish-ethnics who converted to Judaism, it's clearly not just Jewish blood. But blood relations are the strongest ties in the religion, and removing the basis of this would severely weaken the fundaments of Judaism.

While that sounds dandy, this also means if Jewish overlords really crank up the planetary dystopia, they can forcefully genetically edit anyone into being Jewish, especially white supremacists, and if they corner the genetics industry, Jewish blood will spread like a world economy crashing virus.

Where do the genetic hijinks go from here? How would either side react to such subjugation? Obviously Jews will craftily look for ways to beat all sides of gene tech oppression.
