rat genetics

hi

well, it seems the petstoreclerk sold me a female rat, (yeah great, i love
petstorejerks... hehe) - now the problem is, she got pregnant - i know...
she had her litter last night, 12 of 'em, all great looking, alive and
kicking so to speak - or squeaking.

i think the father is my blackhooded male (since he is the alphamale) and
she is an agouti - now i was wondering, which colours am i to expect?

any help would be appreciated. :)
