Stripes vs. Motleys: My experiece with them.
The relationship between Striped Corns and Motley Corns is not fully understood. I know that I do not completely understand the two genes relationship and I am not so sure anybody else does either. Are they different genes that are located on the same locus, or are they the same gene? Are there any secondary recessive genes that make the two look different? What do Hets for Motley and Striped look like if we go with the allele theory? Can pure Motleys have striping? Can pure Striped Corns have broken stripes? What is a “Cubed” Corn? What does Striped Motley mean to you? I am sure that it means something different to me than most at this time.
I have a lot of experience breeding Motley Corns and quite a bit breeding Striped Corns as well. I began breeding Corns in 1982, so I saw the Motleys and Striped come on the scene in the Corn Snake World. Unfortunately, my memory is not perfect, but for the most part Striped Corns and Motley Corns were sold as different genetic traits and bred to the same genetic morph most of the time as far as anybody knew. If somebody mixed the two, how would anybody know several generations later, since they have been around for close to 20 years. A better question would be: If Stripes and Motleys are different genetic traits, it should be easy to isolate each one out with test breeding, but it doesn‘t seem to be that easy? Double hets for Motley and Striped X Double hets for Motley and Striped should produce 25% Motley, 25% Stripes and 50% Double Hets for Motley and Striped. Is this what happens?
My first disagreement with most thinking these days is that a Motley with Striping is actually a product of a Striped X Motley breeding that would in fact be a double het for Striped and Motley, if we subscribe to the allele theory. When I first started breeding Motleys along with many other breeders, we began to see a few small connected blotches of dorsal pattern that we all thought was pretty cool. The rest of the snake looked very Motley like. These small sections of striping were thin and usually had irregular edges. Of course, we all saved these partial striped Motleys and as time went on, selective breeding produced more and more Motleys that had dorsal striping. Four Line Striped Corns were never produced from these Striped Motleys and eventually, fully Striped Motleys were produced which had nothing to do with the Striped gene at all. I produce a lot of Motleys that have dorsal striping these days because I have been selectively breeding for that trait for many generations and it has nothing to do with the Striped gene at all. The stripe is narrow and usually has irregular edges, but not always. I have produced some Snow Motleys with a perfect thin dorsal stripe down their back that was not irregular and looked very much like a perfectly striped Amel California King Snake. Why does almost everybody who sees a Motley with dorsal striping these days, automatically think they are a double Het for Motley and Striped? Pure Motleys can and do have dorsal striping that is a product of selective breeding, however it acts much more like breeding Aztecs. It is not predictable. If any one of the breeders has some striping, many of the offspring can have striping or almost none at all. Fully Striped Motleys bred to the same will produce some completely normal Motleys, but generally many more of the clutch will have striping.
I have been producing quite a few Striped Corns over the last few years. I have to agree with most writings that I have seen that a fully striped Corn is fairly rare. I only get a few in each clutch. Most of the clutch is half striped, or fully striped with broken stripes and some with the odd looking “Cubed” Pattern. Many only have a hint of striping on the neck which fades into a pattern less snake. The Amel Striped Bloodred at the beginning of this post looks to me to be a Genetic Striped Corn that starts out with good striping and then begins to break up and has the Cubed pattern towards the tail, but it looked like a Motley to someone else and others probably as well, but why. The Stripe is not narrow and has regular edges. The blotching on the lower half of the snake does not resemble the pattern on a Motley Corn does it? If the stripe on the first part of the snake connected and continued down the back, it would be a fully striped Corn. We see a lot of photos of very nicely striped Corns, but are they the select few or is the entire clutch fully striped like the ones in the photos?
The Motleys and Striped Corns in my collection were bought as pure genetic types. I have produced some Motleys with dorsal striping and patted myself on the back for my efforts, but it was due to selective breeding. I have never produced a Four Lined Striped looking Corn from my Motley line. I have produced a lot of clutches of Striped Corns, but I can’t remember one that was a full clutch of fully Striped Corns. Most were partially striped or near pattern less and some looked like the “Cubed” Corns. I have never produced a corn from my Striped Corns that looked like a typical Motley Corn to me, not one.
I have bred Striped X Motley and the results were very surprising to me. I still have a few of these females that bred for the first time for me this year. I bred them to Motleys and typical Motley babies were produced. The breeding that produced these females was an Amel Striped X Motley het amel. The results were 25% Amel Motleys, 25% Motleys and 50% Amels and Normals. Yes normals! I have no idea why. Not one of the Motleys had any striping at all. The babies that I produced from these girls this year are plain old boring Motleys and nothing more. Are “Cubed” Corns a result of a Motley X Striped breeding? I have seen the “Cubed” Corns listed as “Cubed” Motley Corns, but I have never produced a single “Cubed” Corn from my Motley line. I have produced “Cubed” Corns from my Striped line, but not one Motley. In my opinion, the “Cubed” Corns are a product coming from the Striped line and not the Motley line, but I suppose if the two were mixed you could get “Cubed” Corns from Motley looking breeders.
Here are all of the photos that I have of the Striped Amel Corn that I used to start my Striped Lavender Project with. I sold him to a wholesaler last year because he was getting old. I bred him to a Lavender Corn that turned out to be het for Amel which I bought from Tim Rainwater, which produced Normals het for Striped Opal and Amels het for Striped Opal. I bought him from Lloyd Lemke in 1990 as an Amel Striped Corn. He had the most complete striping of any that Lloyd had at the show at the time. As a hatchling, his striping was very good on the first half of his body, but faded to mostly pattern less towards the tail with random areas of blotching.
