You should really find out what strain she is. There are 3 phases of albinism.
Strain 1 has 3 colour variations, white phase lavender phase and purple phase (this is the strain of your purple albino)
Strain 2 looks pretty close to a white phase retic

Strain 3 looks like an amel, it was originally albinoXamel but the amel took over.
You cant breed one type to another and get albino young, you just get hets.
