Retained sperm?

i was working all day(18hrs) today and thinking a lot about my next females to buy that will work great with my future breeding projects. so heres the situation, i have a black pastel het albino male, and albino female. Say i breed them and get a male albino black pastel. i then breed that to my pastel lesser, and i get those offspring. but next breeding season i pair the pastel lesser with a killer bee(which is my future breeding plan), and i get a normal baby. But with the breeding of a killer be i should only get babies that have the pastel gene(aka no normals).
So would it be safe to say that the female retained sperm from breeding season before from the albino black pastel. resulting in the normal baby be 100%het albino? Or could you not be able to guarantee the genetics of the normal being het albino? even know i will most likely hold on to the baby and just keep it a normal. i just was wondering if it would be 100 het.
if any of this is confusing let me know ill try to explain it better.
Thanks
Tom

You got it right. If the pastel lesser is only paired with an albino black pastel and killer bee any normals that hatch from her will be het albino.

Any plain lessers she produces will be het albino as well. The only ones you won't be sure of are pastels. You could get regular pastels from either pairing so they would be possible het albino - not sure what % to add if you're factoring in possible sperm retention..

I guess if you get a double sired clutch(confirmed if you pop out stuff with black pastel and spider) the pastels would be 50% possible het albino. If all babies have pastel in them though I wouldn't even put a possible het stamp on any of them since I have no idea the odds of retaining sperm.

It's late and now my brain is hurting, don't blame me if I muffed it up somewhere.

thanks john for the help
