It's easier (in my head anyway) to think of it this way:
First, I'm working with only one incomplete dominant gene, so half of the offspring will carry it, and half won't.
- 50% Butter, 50% non-Butter
Next, I'm working with one visual recessive parent, and one het recessive parent. Half of the offspring will be visual recessives, the other half will be hets.
- 50% of the Butters will be Genetic Stripe, the other 50% will be het Genetic Stripe
- Same goes for the non-Butters - 50% GS, 50% het GS
Drawing this out to its conclusion will give me the following results:
- 25% Butter Genetic Stripe, 25% Butter het Genetic Stripe, 25% Genetic Stripe, 25% het Genetic Stripe
