Yes, we know it, which is why we're able to explain it to people who don't. You know it too, so why are you unable? Actually I think the second time was more accurate, but I also think this would work: http://www.ball-pythons.net/forums/s...ad.php?t=52847
"het" is (almost always) referring to a carrier for a recessive trait; I think "het" is distinct from "heterozygous" in this sense. But I also think it's good to explain said distinction.
