I found the information and this weekend ended up meeting an aquarist at the CAS spring auction that has been raising true albinos for 20 years. (HAH! How's that for lucky? Maybe I should play powerball too?) Anyhow, he was talking about the very same subject. It seems that the line does seem to throw colors and revert more and more in subsequent generations. I'll see if I can get more info from him, also a name and e-mail for you. He sounds like he is going to try a new strain, this time HB's, half-black and whites. I'll bet he has some fascinating insight on the subject. In fact, sneaky me I asked if he'd be willing to sell some. He is, and is bringing them to the next meeting on friday. (I'm now an official member of Colorado Aquarium Society.)
The other information can be found online. I found an albino line diary, of sorts, at this url http:///www.world-guppy.de/english/article1/topswords.htm
The article is by an English fellow by the name of Alan Charlton. On page 10 of the article it seems that his line of 15 years threw albinos, blondes and greys. He has pictures posted, too. It was originally a cobra topsword line. He ended uptrashing the albino line after many failures and interestingly enough, by default, improved his blonde line. He talks about several later attempts at the albino topsword line. Interesting article and he even has pictures of albino fry. He mentions a lady named Midge Hill who has woked on the genetics of albino guppies. As it turns out, there are two genetically distinct types of albinos in American guppies (type A and B), and a third type in Singapore (type C). As it turned out, Alan had all three gene types present in his tanks!
You were right, the albinism results from an inherited inability to produce the black pigment melanin. I had to snicker when he mentioned that a lot of albino mammals have eye defects, which produce a pronounced squint. How would you detect a squinting guppy? :)
