Snow questions

[Raven]

I'm hoping that someone can clarify or explain a few of the differences in the "snows". I have 3 currently. Here is what I was told they are - green spot, snow and coral snow. They are all very difficult to photograph and show their true colors so I unfortunately used some decent older pictures until I can get better ones.

I understand that coral snow has an extra gene giving it the pink, but is there any way to tell if he's coral, strawberry, bubblegum etc by just looking or am I fine to believe he is what I am told?

As far as the standard snows are concerned, is green spot just a variation of snow? What factors give the two such different coloration? My "green spot" as she aged became pure white with a white pattern. The standard snow has the typical peach color sections I have seen online, but these are becoming what I can only describe as bright tangerine.

Thank you in advance for any help!

I'm not sure why the images did not show in the original post. I think they are showing below.

While I'm not 100% certain that strawberry doesn't cause some pink coloration in coral snows, I can guarantee it doesn't cause excessive pink. Current speculation is that there are multiple red factor genes, but this is difficult to prove for obvious reasons. Bubblegum could possibly be a different strain of red factor, or just one with polygenetic differences from selective breeding or even natural variation. Best guess, without seeing the photos, your tangerine-ish one could be a salmon, most likely with selective breeding to enhance the coloration. Marsha of Poppycorns once wrote to Don complaining that they had overdone red factor in salmon snows, rendering a bright orange-pink tint rather than a more desirable magenta shade.

(e) Google Drive is great for sharing person to person but isn't meant for hotlinking, so that's why the photos didn't show before. Your green blotched snow still looks fairly typical, but they do fade a bit as they grow and age. The bottom one is at least a coral, very likey has at least one copy of the red factor gene, possibly two. The second could be selectively bred for the pink, since red factor tends to take over the background as much as the saddles. It could also be red coat instead. A lot of trial breeding would be needed to make even educated guesses, and even then you might not find an answer.

Thank you. What is my best option to see what gene or genes are controlling the change of color for my snow with tangerine? I will try to get a good picture of him in a few days.
If he is possibly not true snow, and my female (green spot?) Is not either, what should the ideal snow look like?

 

[Raven]

Guess I will have to learn some better ways to upload my pictures then!
I just did some research on Red factors. Do you know of decent websites/articles on the subject?

I'm not sure what you mean by "true snow"? All three are snows, being homozygous for amelanism and anerythrism. Asking what an ideal snow should look like is like asking what an ideal amel should look like...there's so much variation, and not everyone agrees. Personally I'm rather fond of pink snows.

As for red factor, I'm afraid there isn't a singular archive on it. I would do a search on these forums as well as searching cornsnake.net, but be aware that older information could be wrong or misleading so take everything with a grain of salt. The only red factor I currently feel comfortable working with is Don Soderberg's cayenne fires, which surprisingly haven't been outcrossed all that much (I'll fix that ) because it's from a known line and has a proven mode of inheritance.

Thank you! That makes sense. I guess the names are what trip me up because I understand the genetics abs inheritance aspects. Just trying to sort out the who's who/trade names but your explanation helped.
I've read a lot of very confusing abs conflicting information regarding the red factor/red coat/ diffused/blood red. Same for amel. The variations are extensive and the influence of different genes, even recessive hets, can have a big influence.
Just trying to sort it all out, be able to recognize what I'm truly looking at, and predict genetic combinations.
Are there any known lethals like there are in other species? (Such as breeding two blue merles in dogs)

I tried to capture the tangerine color, but it was very difficult. This is the best I could get. It is much more pronounced/bright in real life. I will also try to find his baby picture. That may help as well?
