I never really bought into the "dominant/recessive" thing, not only because it's nonsense, scientifically, but because it was unimportant plot wise. All that mattered was that Liquid believed he was made inferior, to provide motivation for his character. I wouldn't be surprised if the science aspect was deliberate misinformation, and that there was an entirely different reason as to why Solid Snake was considered to be the inferior one by Ocelot in the MGS1 ending.

As for failed batches, Big Mama mentions these in MGS4, but yes, she may not be privy to all information on LET.
