What would be the result of breading two albino 50% hets...also how do you figure it out.... say you have homozigues instead of het... or 75% to 50 % het like someone please explain to me the whole concept of it all please!

It depends on whether you actually have hets or not. If you do, in fact, have 2 hets, you will get:

1/4 albino
1/4 normal
1/2 hets

or, rather:
1/4 albino
3/4 66% hets

That's a best case scenario. Worst case, you get all normals because your breeders turn out to not be het. If you have just one het, you get half het and half normal (or all 50% hets).

It's all genetics and is dependent on if there is anysort of co-dominant gene invovled. But generally, it all depends on a number of factors, for example, number of offspring, genes, and the trait. It's hard to tell...but generally if two 100% het's (Aa) breed, you'll generally get one normal(AA), two 100% hets(Aa), and one offspring that is recessive for the gene(aa). (AaxAa= AA, Aa, Aa, aa). But remember that the normals and het's look alike, so it would be considered 66% het. (66% of the normal offspring should be het.) Now, if you have a 50% het mating with a 50% het, the chances of getting a recessive offspring are kind of low. Instead of 1/4 offspring being recessive, it'll be more around 1/8 offspring. If you breed a homozygous (AA/dominant) and a 100% het, you'll get (AAxAa=AA, Aa, AA, Aa). Since all of these appear normal, the offspring would be 50% het.

Sorry this is confusing.

I mean, you're eaither going to get about 1/4 or you aren't going to get any, depending on whether or not you actually have hets. I think averaging the two outcomes like that is confusing.

Yea, I think you're right now that I think back on it. It still very dependent on the two parents. I mean, if they are both 50% hets, the chances are kind of slim.
