Epstein-Barr Gene-Lock

"So, with this Epstein-Barr gene-lock, we stopped the Reds and the Ginger's attempts at taking us over?"
"That's what we're told."
"You don't sound convinced."
"I found some... troubling evidence."
"Like that?"
"That whoever invented the gene-lock was a Red herself."
"So there's a lock, but it's anyone's guess if it's working?"
"Yeah, she just so happened to be leading the tests that 'proved' the gene-lock actually stopped gene-expression the way it was supposed to."
"Shocking. And how do we make sure?"
"She's been dead for twenty years, it's not a path open to us. But if anything, red hair is even more prevalent, in gene-lineages that were purely black-haired or purely blonde, for that matter."
"Corruption of the lineages?"
"No, that's constantly checked for."
"And if she was that high, that connected, she couldn't tamper with that?"
