I’ve heard that banana combined with the BEL genes (Mojave, Butter, Lesser) can result in reduced or no spots. I’ve seen some adult bananas with multiple genes and no spots but it could be hard to predict whether or not they will get spots when they are babies.
If you decide not to go with banana, there are some lookalikes like Candy, Toffino, and Lavender Albino which don’t get spots.
