OMG!!
You've just triggered conception of a new technology for key exchange.
Relatives can use their shared DNA, focusing on the highly variable parts of course, combined with calibrated redundancies in the message (depending on how closely they're related), to perform key exchange. Implementation details are self-evident I think.
Obvious vulnerability is if they or any of their relatives are ever captured, or shed a hair in public.
