Eh. I'm not sure that's the right interpretation of what's going on here. Jewishness is kind of famously not genetic. A lot of groups ascribe Jewishness as passed down matrilinealy; If your mom was Jewish, you're Jewish. And Israel's laws on who is Jewish are kind of a mess. I assume this is just people who want genetic descendants for normal whatever it is that makes people want biological descendants (I've never really understood it) reasons and some news writer thought it was get some clicks.
