Heres a corn I produced in 2004 getting in touch with her dinner!!This snow corn was produced by a male pastel motley and a female ghost motley.(hypomelanism present)It's truly a striking snow corn and the pik doesnt allow full appreciation of it.It has a faded wash over the entire body and the colors really get spirited away making it look like a ghost or almost lavenderish color, kinda leaning towards some Opal corns.She is ready to breed this year and I expect some cool looking offspring from her!Can't wait!!!!!!  I'm hoping to weed out the yellow in future breedings to get it to a more pure strain of pinks.I got a type b anery now that she will mate with to help rid the yellow I'm hoping , even though I like the look of the yellow.  |

I actually like the look of the yellow with the pink. My male snow has yellowish saddles, so I call him my dog-piss snow.
How do you plan on using your type B anery? I'm curious because they have an unknown quantity of potential yellow pigment, they're just not expressing it. If you want a snow (i.e. Type A anery + amelanistic both expressed) to have pink, they need to have to potential to make yellow as well... is you have a blizzard (type B/amel homozygous) then you'd lose your pink. If you have an amel homozygote that's het for type a and b, you're just going to have an amel. If you inbreed until you get both a triple homozygous animal, I think type A is largely epistatic to type B, though not completely (considering we keep trying to apply mendelian genetics to these animals with absolutely no idea where the genes are in the chromosomes and no long term dada to even prove they're mendelian, I don't have much faith in it) It seems like you'd be better off getting a known type A that has extremely reduced yellow, and then using him. I have no doubt that in most cases the extent of pigmentation (i.e. the thickness of saddles) is an additive effect of multiple genes, so it'd be better to have halvsies in each offspring that are from an animal you want, assuming there's high heritability of the trait.

Like you said " I'd be better off using a type a anery with reduced yellow".I figure why use a reduced type a when I have a type b with no yellow present showing.Yes I'm aware that some type b harbour the yellow and can even show as much as a type a in the case of yellows.Lets not forget that dietary supplements such as cratenoids, may effect a snakes coloration as well.Not only does the type b have less or no yellow it has a slight purplish pink cast to it like a pastel and the type a has none and usaully don't have any reddish pigments at all unlike a type b.(none in my collection)Yes both types are anery but we cant deny that the type b has more possibilities I think.Blah blah ...Genetics!!!I love genetics , but lets face it unless you've done countless breedings bak and forth you will never know exactly what traits your snakes have hidden and how many things they are actually het for.Lots of test crosses and years.Anyways I appreciate your opinion , but I dont want to get into a genetic war!!!HA ha ....., no seriously , thanks for your input.

The enhanced pink is pretty typical of what are now being termed 'coral snows' that are snows homozygous for hypo A - which yours would be if the 'pastel' motely was a ghost motley. Some anery motleys are also sold as pastels because they can have pretty similar coloration. Either way, looks like a good chance your girl is homozygous for hypo A - very pretty example.
The motley gene also alters the expression and intensity of most colors when it is present - should make for some nice offspring from her in the future.
Have to agree that anery B can show quite a bit of yellow though I don't think it is well established that those that do are not also homozygous for anery A. Our blizzard male has a lot of yellow - will be test breeding him this year to determine whether he is het or homozygous for anery A as well.
Genetics certainly has advanced a lot in corns but still tons to figure out. Look forward to seeing more pics of your collection.
