Description
Design set for Oxpecker.Larger version will be sent to their owner only.
About their genes
These are all first generation crosses. So they are Akhal Teke x Appaloosa horses. It is thought that PATN1 (Pattern 1) causes Leopard Spotting, and PATN2 (Pattern 2) is Blanket. The LP gene is thought to be a trigger switch which allows for the Pattern genes to show through, and it is also through to be the cause of Varnish roan. Tho it is not sure how varnish roan in controlled as some horses show minimal signs, and others varnish with age.
There are also though to be pattern suppressing genes so Near Leopards can be leopards with a suppressor.
It is also thought there is a dilution gene in some appaloosas which dilutes black to a brown color. This gene is not Silver, it is currently unknown.

Forgot to mention, I've never met an appy in RL that wasn't fully varnished. So I'm just wondering if non-varnish appys actually have a little bit of speckling around their blankets once you get up close or once they age?

I couldn't remember if I said the line art and maker was yours? Just need to know if you don't want to see this in the Free Coloring book at JF Studios.

No, I only paid for the coat designs. I remember you mentioning how you wanted to use these lines for the colouring book.

Ok, good. Just making sure LOL

There are plenty of horses which do not varnish, some that varnish with in the first few years, and some that varnish years later.

After reading deeper into appy genetics I’m a little fuzzy on a few details. Mind if I run some observations past you just to get this straight?
(To shorthand, I’ll number these designs from left-to-right going down the picture like you would read a book)
- Designs 1 and 6 are near-leopards because their PATN1 is heterozygous? In theory, a homozygous PATN1 would be patterned from head to toe. Is this the rule, or are there fully patterned heterozygous leopards too?
- OR, are designs 1 and 6 not full-body leopards because they carry E which suppresses or reduces the scale of their patterning? So if you theoretically switched off the E they would probably be full-body chestnut leopards.
- OR, are you making reference to an unknown suppressor which pushes the blanket back away from the head/chest?
- Some appys exhibit no varnishing whatsoever, due to unidentified suppressors. Is this true, or do all appys show some minimal degree of varnishing?
- Does PATN2 (blanket or snowcap) ever go past the shoulders? If not, shouldn’t design 2 be heterozygous PATN1?
- Is there a seperate PATN loci for snowflake, or is it just a subdued expression of LP varnishing?
- The appy black dilution is is typically a chocolate-labrador colour with a kind of bronze sheen? (examples other than Sprinkles from EquineTapestry: [link] [link] ? -- not too sure about these ones: [link] [link] )
Thanks for reading

There is a theory that a suppressing gene cause cause a P1 horse to not be fully leopard. Like wise, a P2 blanket can also extend past the withers in some horses, this is believed to be a result of sabino or intensifier gene. You can make 1 and 6 recessive for a suppressor gene and have their offspring be full blown leopards.
I do not know much about the extension genes effect on white patterns, there are a few articles out there, but I don't think it's a solid rule because working with an appaloosa breeder, I have seen plenty of horses which do not support that idea. So I guess it's a theory about a trend or pattern they are seeing?
Well........since LP is what causes Varnishing, as well as Characteristics, you could say that mottling characteristics ect, are a type of varnishing, so that said, they would show. However there are no tests yet, and not that much is known about the genes. I have seen plenty of apps which do not varnish out, some that varnish out a little, and some that varnish out entirely!
Design 2 has a spotted blanket. Some times varnishing causes more spots to appear, but treat him as if they are a spotted blanket which has varnished out.
The idea is that Snowflake is a stage of varnish. Like how grey has different stages of greying. In Capalls, I treat snowflake like it's a mutation on the LP gene.
There are a few "dilute black" horses out there, but no one has established if there is a link or not between the breeds. Basically it just lightens the intensity of black. It doesn't make them brown, but like a deeper grulla color, minus the dun characteristics. Just like if you were toning down the darkness of black with a wash of some kind.

Sounds like there's a lot of creative freedom in breeding virtual appys since so much is unknown. This is all extremely helpful, thank you very much!

Once again, I really love these!
I appreciate the info on appy genetics too, I need to read up on how they work.

As I understand it:
LP in a horse with no Pattern genes will show Appaloosa characteristics.
Sabino or a double dose of LP causes an increase of white pattern and smaller spots.
Sabino can be the cause of False few spots and blankets.
Pattern 1 and 2 are on different Loci, so PATN1 masks 2, but both can be inherited.
An LPLP horse should varnish out, but even LP horses varnish. So I think that just has to do with other genes.
There are thought to be white pattern suppressing/enhancing genes.
There is a unknown dilution seen on Black and Bay/Brown appaloosas which seem to fade out their color.
I'm sure there is more, but I'm just not up right now. But this is all current theory. They are hoping to have tests soon, but they have been working on this for years now.

Thanks for that! I'm going to hunt around on google for more resources now.

equinetapistry.com an equine color blog has some articles. I think I posted a link on one fo the comments on this deviation.

Beautiful, BEAUTIFUL patterns! Love it! Apparently Akhal-Teke/Appy crosses (aka Nez Perce Horses) are getting quite popular!

I love the dalmatian spots on their booties & this is a nice pic too.

oooh pretty. Appy designs always were a massive challenge for me.
And I see genes here I'm not familiar with. Will there be another news article in the future? I'm a sucker for this stuff now because of you. XD

I updated some gene information. I am not comfortable enough right now with the genes to write a full blown article on them just yet. But there are some articles already written which are really informative [link]

I screwed it up; should have read "vend-a-horse", because of the ability to custom design a horse. It's not a very good joke...but I love the art work. It's a wonderful depiction of the incredible variety and beauty seen in the horse.
