So breeding an albino to a normal makes all normal looking babies that are 100% het for albino
Breeding a co-dom such as a pastel to a normal will technically yield 50% Pastels and 50% normals but thats genetic punnet square figures and certainly not what can happen in real life.
The Genetic Stripe has two copies of the Genetic stripe gene which makes it a visual.
It contributes one of the two to all of its offspring - so it doesn't matter which of the two it contributes, it's still contributing one copy of the gene, making all offspring 100% het, whether it's bred to a normal or any other mutation.
