That is actually suspected by a few breeders...so you're not crazy!
The problem is, no one is really sure what the "new patternless" gene is. I can think of at least one breeders who produced some very APTORish babies without actually breeding an APTOR. His baby was produced by crossing a Stripe x Reverse Stripe.
He is testing this out, but it seems the stripe and reverse stripe are the keys to a polygenic trait - the so called "new patternless". I prefer the other name - "patternless stripe"
