The 3 reproducing offspring of the original carriers (2 to 1 carrier/non-carrier) would produce an equal number of carriers to non-carriers (16/16). So the ratio is reduced to 1 to 1...and so forth...the odds keep going down.
I think that's right. Other recessive traits rely on the person with the trait reproducing. Otherwise, the trait just becomes more rare. I know, you got the idea, LOL. But the math kept bugging me.
Either they're in denial or hiding it, like James Hormel, or "ex-gay", like John Paulk.
