If an Albino Male is bred with a Spider Female then it will produce in the clutch:

50% Spider Het Albino
50% Het Albino (normal looking)

If I was to take a Spider Het Albino Male from this clutch and breed it with a Het Albino Female (normal looking), then what will be produced?

Albino spider, albino, spider 66% het albino and 66% het albino based on 1 in 8 odds.

I'm using a matrix of 8 sections to the Punnett square so there's a 1 in 8 chance for each possibility. For example, 3 chances out of the 8 can yield a spider and two of those spiders will be het albino and the other one will just be a spider. That's where the 66% het albino comes into play (2/3 = 66%). Apply that to the 66% het albino mentioned above and when you add the possible combinations, you'll see where the 8 possible combinations come into play in my original answer above.

There's a good bit of knowledge on the Internet about the "Punnett Square" and how to apply it with determining pheno/genotype's. You should come up with a variety of articles and educational materials if you Google "punnett square".
