Albino x black pastel het albino

[DKPythons]

Can some one enlighten me, as I seem to be a little confused about this topic at the moment.

I would like to pair a albino with black pastel to get plack pastel het albinos.

If i pair back the pastel het albino to the albino, I presume I get something like:
25% normal
25% normal het albino
25% black pastel het albino
25% albino

Am I right?

How will it look when I pair pastel het albino x pastel het albino?
The catch would of cause be to produce blizzard (super black pastel albino)
