I dont know much about the way herpers like to say it, but being as i'm big into biology (currently pursuing a marine bio degree) i have seen it mostly as "heterozygous Albino" or heterozygous for Albinism (yes it's a word... i promise haha) ... but if you say any of those i assume people would know what youre talking about
I agree with Lauren it is "heterozygous for albinism". I am currently pursuing my degree in biology too and genetics is such a fun class to take. Either way we love our albino hets, het albinos or however you want to say it. Because they make beautiful babies!! Right?
Okay, I'll try to remember to use Heterozygous Albino or Het Albino because "Heterozygous for Albinism" sounds a wee bit nerdy. The kids on the playground would probably beat me up for using it.
As a biologist and a language freak, here's my take:
While 'heterozygous for albinism' is a mouthful, it's the most accurate; 'heterozygous albino' is also correct. 'Albino heterozygous', though, is just wrong -- 'heterozygous' is an adjective, not a noun. You'd have to say 'albino heterozygote' and, while that's correct, it doesn't actually provide any link between the albinism and the heterozygosity -- it could be an albino (ie, full albino) which is heterozygous for some other trait.
Cheers.
