As far as I'm aware:
Yes, motley and stripe share the same locus.
Yes, motley is dominant to stripe.
A visual motley het stripe does not HAVE to have the 'ribbon motley' pattern.
"Motley Stripe" is usually what I'm referring to as "Ribbon Motley" - which is one of the many motley patterns that can occur in homozygous motley animals as well as motley het stripe animals.
I'd kinda thought that Banded was a selectively bred motley pattern, but I wasn't sure.
Frosted, to my knowledge, is something else entirely that can be either selectively bred - or show hybrid heritage.

Motley and stripe share the same locus.
The current theory is that motley is dominant over stripe.
Exactly what "motley stripe" is can depend upon who exactly you are talking to. The cornsnake world is trying to agree upon the exact wordings and definitions when dealing with this particular pair of genes. I'll try to help by giving the terms I am currently using or have used in the past year:
Motley/stripe - snake is carrying one motley gene and one stripe gene.
Motley het stripe - currently preferred terminology to avoid confusion when dealing with a snake that has one motley and one stripe gene.
Striped motley - homozygous motley showing the striped pattern of motley (may mean the same as pin-striped motley).
Pin-striped motley - homozygous motley showing the pin-striped pattern (may mean the same as "striped motley".
Q-tipped motley - homozygous motley showing the Q-tipped pattern of motley.
Hurricane motley - homozygous motley showing the hurricane pattern of motley.
PLEASE NOTE: A cornsnake that is motley het stripe can show ANY of the above mentioned pattern types. Also, any given cornsnake can show one or more of these pattern types.
Examples:
"Typical" homozygous Motley pattern (with Q-tipped pattern by tail)
Q-tipped homozygous Motley
Striped homozygous Motley
Motley het striped
Motley het striped

heterozygous for both Motley & Stripe would be ms

Just thought I'd post a couple of pics. These are motley x stripe ghosts from breeding a motley x stripe to a stripe. They almost look like stripes but they aren't... This is why I like to say motley x stripe instead of motley het stripe. I know the theory is that motley is dominant, but if you were to go by their appearance, it almost seems as if the striped gene is stronger than the motley in some of the ms babies I've produced!

Not quite. Motley is still a recessive-to-wildtype gene and is written as a lower-case letter even when it's dominant to the other gene of the pair.
Motley is, for all appearances, dominant to stripe and motley certainly can hide stripe.
It just happens that there is a motley pattern that IMITATES stripe. Susan's posted some photos of motley het stripes who don't show any sign that they are het stripe (and homozygous motleys who have the striped/ribbon/pinstripe motley pattern) - and other folks have posted photos of ribbon/pinstriped motleys who are known to be het for stripe.

susan, just one question for my understanding.
i breed amelanistic stripeds and motleys from a pair of amelanistic motleys (both what you would call the q-tip pattern) for several years now. shouldn't a simple recessive trait like striped vs. motley result in 1/4 striped vs. 3/4 motley? my results differ by far, it's definitely closer to 50% than to a quarter every single year and in total. 39 of 84 in total is a statistically relevant difference. but might still be coincidence, ok.
the stripeds i get from these are mostly "perfect" stripeds with the four small lines that are straight, parallel and the same size from neck to tail.
i don't count motley stripeds as shown in your examples as stripeds. if i count these to, then it's real close to 60%. i try to add a pic or two that explain what i mean. how does that ratio work?

Statistics say that pairing two motley het stripes would result in 3/4 phenotyic motleys (1/3 homozygous motley and 2/3 motley het stripe) and 1/4 stripes. If you're getting closer to 50% stripes, one of several things are happening:
1) One of the parents is not motley het stripe but instead is homozygous stripe.
2) Some of the hatchlings are being mislabeled as homozygous stripes when they are actually motleys (homo or het(.
3) You've been beating the odds so far and should consider yourself lucky. Next year, you may not get any stripes from the pair. (And Murphy now knows you're there and will make sure of it...plus make the hatchlings all of one sex.)
