Yes, Carlos Flores in my lab did something like that. Except that it was
easier because we knew the deletion homozygotes lived to the pupal stage.
He used the Tubby marker to pick out pupae that had the deletions and
PCR¹d them with primers suspected of being within the deletion along with
some positive control primers. It worked fine.
